IFIMUP researchers at the PSI, Switzerland
IFIMUP researchers at the PSI, Switzerland
Researchers from the IFIMUP Polarisable Materials and Functional Nanostructures group were for the first time at Paul Scherrer Institute (PSI) in Switzerland for muon spectroscopy beam time, within the "Internal field distribution in TbMnO3 and TbMn0.98Fe0.02O3 single crystals: the effect of modulation and disorder" proposal in collaboration with colleagues from the Center for Physics of the University of Coimbra, from 29th of November to 3rd of December.
At PSI, the researchers used the muon spectroscopy to characterize the distribution of internal magnetic field, due to the concomitant effect of incommensurable spin density waves and the presence of several magnetic species, to reach a deeper understanding of the remarkable changes occurring in the magnetic spin structure of TbMnO3, inherently connected with its ferroelectric properties, via the magnetoelectric effect.
The expected measurements will also allow to build a complete picture of the distribution of internal magnetic fields at the muon site, indispensable for the assessment of the effect of applied electric fields and high-magnetic fields in the muSR signal, which is envisaged in future experiments.

IFIMUP’s future plan in the news
IFIMUP’s future plan in the news
Professor João Pedro Araújo, actual president, talked with the Perspectivas, supplement of the Público national newspaper, about the future of the institute. He explained that, after three decades of existence, a new strategic plan aiming for a higher international impact is in course. In the future, the research will be focused on the areas of condensed matter physics and materials with the opportunity of technological applications, with the institute having the new designation of Institute of Advanced Materials Physics, Nanotechnology and Photonics (starting in 2019). The three groups are kept in this new approach. The Multifunctional Magnetic Materials and Nanostructures group assumes as central topic the creation of magnetic (or non-magnetic) materials with applications in areas such as technology used on the hard disc's reading process, for example, and, more recently, in new forms of energy harvesting. The Polarizable and Magnetoelectric Nanostructures groups will direct its interest to dielectric systems, that is, polarizable materials by the existence of electric charge instead of magnetism. These two groups link their work in the topic of multiferroic or magneto-electric materials, which combine the two properties. Finally, the Ultrafast Lasers and Magnetodynamic Spectroscopy group, recognized for having a vast know-how and state-of-the-art laser technology reaching from the femtosecond to the attosecond, will concentrate its study in the search for techniques to measure physical phenomena at these ultra-fast scales.Furthermore, he stated the three great research branches, in which the groups interact in an articulated way and in collaboration, that are in the plan for the future: Quantum Materials; Advanced Materials for Energy; Materials and Ultrafast Lasers for Biomedicine. For this purpose, collaborations with the Institute of Innovation and Health Research (I3S), the International Iberian Nanotechnology Laboratory (INL) and the Institute of Pathology and Molecular Immunology of the University of Porto (IPATIMUP) will be pursued, as well as connections with companies, such as HBM FiberSensing and EQS-Energy Quality and security.The article also comprises information about IFIMUP’s spin-offs (Sphere Ultrafast Photonics and InanoEnergy), that hold patents and international recognition, and the Network of Extreme Conditions Laboratories (NECL), led by IFIMUP and extremely important in the context of IFIMUP's current and future strategy.

IFIMUP researchers at ISOLDE-CERN
IFIMUP researchers at ISOLDE-CERN
Researchers from the IFIMUP Multifunctional Magnetic Materials and Nanostructures group were from 24th to 30th of October back at CERN, in the ISOLDE facilities for a 111mCd beam time.
At ISOLDE, the researchers used the 111mCd γ-γ Perturbed Angular Correlation (PAC) spectroscopy to study Multiferroic compounds. This technique allows a local probing in the materials structure, through the evaluation of the electric field gradient and magnetic hyperfine field, giving insights of local lattice proprieties and phase transitions.
This group is studying Double Perovskites and Ruddlesden-Popper bulk crystals, materials that are receiving an increasing attention due to the existence of hybrid improper ferroelectricity. The main goal of the research is to understand the origin and how to enhance the magnetoelectric coupling in these compounds assisting in the development of room temperature multiferroic materials.
The work is being performed within the "Local Probing Of Ferroic And Multiferroic Compounds" ISOLDE-CERN proposal having financial support from the H2020-EU 654002, European Nuclear Science and Application Research project, as well as national projects CERN/FIS-PAR/0005/2017 and POCI-01-0145-FEDER-029454.

2018 Nobel Prize in Physics Celebrates Laser Science and Technology
2018 Nobel Prize in Physics Celebrates Laser Science and Technology
Earlier this month, the Swedish Academy announced the award of the 2018 Nobel Prize in Physics to two key laser inventions: Arthur Ashkin (Bell Labs, USA) was awarded half the prize for pioneering the technique of optical tweezers, and Gérard Mourou (École Polytechnique, France) and Donna Strickland (University of Waterloo, Canada) share the other half for their invention of the ultrafast laser pulse amplification technique known as chirped pulse amplification, or CPA.
Interestingly, this announcement comes surrounded by records at several levels: Ashkin, at the age of 96, is the oldest person ever to be awarded a Nobel Prize; Donna Strickland is the third woman ever to win a Nobel Prize in Physics, and the first in 55 years, after Marie Curie in 1903 and Maria Goeppert-Mayer in 1963; the CPA technique allows today the construction of the most powerful devices on Earth – ultrafast and ultra-intense lasers capable of producing light pulses with durations in the femtosecond range (1 fs = 10-15 s) and peak powers of tens of petawatts (1 PW = 1015 W), 1000 times larger than the total power of the world’s electric grid!
This Friday at 14:00 in room -120, Prof. Hélder Crespo, who is group leader of IFIMUP’s Ultrafast lasers and Magnetodynamic spectroscopies group and an Assistant Professor of Physics at the Department of Physics and Astronomy, will give a lecture entitled “Back to the Future: The Physics of Ultra-Intense Lasers and the 2018 Nobel Prize in Physics”.
The lecture will focus on the CPA technique and on how it has revolutionized countless areas of science, technology, medicine and industry, from high-precision eye surgery to extreme physics, where terawatt lasers are used today to accelerate particles with field gradients far exceeding those provided by conventional accelerators, and petawatt lasers (like those currently being built at the European ELI project) may soon enable electron-positron pair production in vacuum, hence creating matter and intense gamma rays directly from laser energy and bringing forth completely new physics. We will also see the strong relationship between the CPA technique and the work that has been carried out at the Ultrashort Laser Pulse Laboratory, Femtolab, home of the first CPA laser system entirely designed and built in Portugal, and where the technique of dispersion-scan, which is behind the shortest laser pulses ever produced, has been invented. The Femtolab integrates the Institute of Physics of Materials of the University of Porto (IFIMUP) and the NECL (Network of Extreme Conditions Laboratories), a new national network devoted to the study of matter under extreme physical conditions, and where ultrashort laser pulses will play a key role in assessing and controlling ultrafast dynamics in matter with unprecedented resolution and under intense optical field conditions.

Dr. Miguel Canhota defended his PhD Thesis
Dr. Miguel Canhota defended today his PhD Thesis on “Ultrashort light pulses over large spectral ranges: novel sources and dispersion-scan-based spatiotemporal diagnostics”. Our warmest congratulations to him and to his supervisors, Prof. Hélder Crespo and Prof. Rosa Weigand from the Complutense University of Madrid. The work focused on the development of new pulse characterization techniques and their application in the characterization of ultra broadband, coherent light sources. Techniques for the measurement of UV (<400 nm) pulses are extremely relevant for ultrafast spectroscopy in chemistry, physics and biology. His work allowed to develop a new inline ultrafast pulse measurement and compression dispersion scan (d-scan) technique based on self-diffraction and apply it to the measurement of over octave-spanning sub-4-fs pulses.

University of Porto funds the demonstration of technologies developed at IFIMUP
University of Porto funds the demonstration of technologies developed at IFIMUP
The University of Porto, through the BIP Proof programme, decided to fund the demonstration of two technologies that involve IFIMUP researchers. The main objective of the BIP Proof programme is to create a proof-of-concept system that aims to stimulate the accomplishment of value-determining steps in the valuation of promising research results obtained in the University of Porto. Such proofs-of-concept can be translated into the construction of prototypes, feasibility or market studies, among others, so as to add value to the research results. In this framework, IFIMUP researchers are involved in two of the nine technologies that the University of Porto decided to fund.
The project "TriboE - Novo sistema de colheita de energia baseada em nanogeradores triboelétricos para a era das Redes de Água Inteligentes" has the objective to demonstrate triboelectric nanogenerators in real environments. This 6 month project will implement a patented triboelectric turbine (Triboelectric Driven Turbine to Generate Electricity from the Motion of Fluids, J. Ventura, A. M. Pereira, C. Rodrigues, C. Alves, F. Falcão, J. Puga, F. Carpinteiro; PPP-109235, 14/03/2016; PCT/IB2017/051473) in water distribution systems to feed monitoring sensors.
The multidisciplinary project “WEStoreOnTEX - Wearables de Produção e Armazenamento de Energia para a Indústria Têxtil”, led by REQUIMTE/LAQV associate laboratory team (C. Pereira and R.S. Costa) in close collaboration with IFIMUP team (A.M Pereira and A. Pires), has the objective of scaling-up a hybrid textile technology that simultaneously functions as supercapacitor-type energy storage and production. This project will accelerate the scaling process towards a fully functional prototype to be tested in a relevant environment. A patent is currently under application to the “Instituto Nacional da Propriedade Industrial”, Portuguese patent evaluation.

Investigation co-authored by IFIMUP-IN researchers was highlighted in Advances in Engineering
Investigation co-authored by IFIMUP-IN researchers was highlighted in Advances in Engineering
The authors proposed to investigate the resistive switching effect that emerges when ferroelectric barium titanate and few-layer molybdenum diselenide are combined in a single structure. They hoped to elucidate the relation between the ferroelectric polarization and the resistive switching effect, and the mechanism underlying the former. It has been seen that the origin of the switchable diode effect can be attributed to charge coupling at the molybdenum diselenide/barium titanate interface, which therefore might be related to the ferroelectric polarization reversal process. A recent study, published in Journal of Materials Chemistry C, on the resistive switching in MoSe2/BaTiO3 hybrid structures conducted by researchers from the Institute of Physics of Materials of the University of Porto (IFIMUP), located in the Faculty of Sciences of University of Porto and a member of the National Associate Laboratory Institute of Nanoscience and Nanotechnology (IN), was recently highlighted in Advances in Engineering.
These results indicate that the molybdenum diselenide/barium titanate hybrid structures are promising candidates for non-volatile ferroelectric resistive memories. Advances in Engineering features papers of exceptional scientific importance and intelligible to a broad scientific audience. The invited articles are less than 0.1% of the whole published literature (that is 20 per week chosen by a team of advisers and experts).

Periodic meetings - 2018 IFIMUP Talks - # 3 presented by Post-Doc researcher Fábio G. Figueiras
Periodic meetings - 2018 IFIMUP Talks - # 3 presented by Post-Doc researcher Fábio G. Figueiras
Next Wednesday, 28th of Februray at 11h30 on room 106 (DFA), Fábio G. Figueiras will give the third session of the IFIMUP Talks series. IFIMUP Talks consists on periodic meetings where IFIMUP researchers present their current state of work, focusing on the open questions and difficulties. The presentation is followed by an open discussion with possible suggestions presented by the audience. Fábio G. Figueiras is a Post-doc Researcher in Physics and Materials Science & Engineering at IFIMUP (University of Porto) and at CICECO-AIM (located at the University of Aveiro). The 3rd IFIMUP Talk will be focused on “Thriving Narrow Band Gap Ferroelectric Oxides for Photovoltaic applications: Bi2ZnTiO6 Thin Films deposited by RF Sputtering".
IFIMUP TALK Abstract:
“The structural, optical and ferroelectric properties of Bi2ZnTiO6 thin films, deposited by rf-sputtering onto Pt/Si-based substrates, were investigated. The thin films grow as polycrystalline perovskite-like phase, exhibiting the tetragonal P4mm symmetry and band gap of 1.48 eV (on the range of Si-based devices). Evidences of the ferroelectric nature of this material which is calculated to reach 100 microC.cm-2 were demonstrated through piezo-response force microscopy. However, this exceptional material is scarcely studied, because it is not easily synthetized using conventional ceramic methods. The results obtained in this work evidences the potential applications of this material for a next generation of photovoltaic and functional devices.”

Sphere Ultrafast Photonics, spin-off founded by IFIMUP researchers, receives Marie Curie grant
Benjamim Alonso has received a Marie Curie grant to carry out a new research project at Sphere Ultrafast Photonics. The Marie Skłodowska-Curie action of the European Commission's H2020 program funds excellent and high-impact research projects, carried out by researchers of recognized merit and potential. This action has a specific panel, Society and Enterprise, established for non-academic beneficiaries. In this call, 58 projects were funded within this panel, two of which in Portugal, and seven more in Spain. Out of the total number of projects, only two were awarded in the field of physics, which includes the one awarded to Dr. Benjamín Alonso and the high-tech spin-off company Sphere Ultrafast Photonics. The project is funded at 160,000 euros for a period of 24 months, which covers the researcher's salary, research-related expenses, and management expenses.
Benjamín Alonso has a Bachelor's Degree (2007), a Master's Degree (2008) and a Doctorate Degree (2012) from the University of Salamanca, having received several awards throughout his research career. During his thesis work, he also completed internships at the Femtolab laboratory (IFIMUP and DFA-FCUP) and later won an individual post-doctoral fellowship from FCT (2013-2014), working in the same laboratory under the supervision of Helder Crespo, researcher of IFIMUP, assistant professor at DFA and CTO of Sphere Ultrafast Photonics. Since then, Dr. Alonso has held several teaching appointments at the University of Salamanca. The project now granted counts with the supervision and support of Helder Crespo (science and technology) and Rosa Romero (technology transfer and product development). It will enable the development of techniques and products at the highest level for the measurement and control of ultrashort laser pulses in the femtosecond range, being a clear example of the capability and relevance that a national high-tech SME can have at the European level.

IFIMUP Seminar presented by Dr. Hab. Oleksandr Dobrovolskiy
IFIMUP Seminar presented by Dr. Hab. Oleksandr Dobrovolskiy
Next Friday, 9th of February at 14h30 on room -117 (DFA), Dr. Hab. Oleksandr Dobrovolskiy will give the IFIMUP seminar entitled “Super meets Nano: From nanopatterned superconductors to fluxonic metamaterials seminar”. Dr. Hab. Oleksandr Dobrovolskiy is a physics researcher and an Assoc. Prof. at the Faculty of Physics of the Goethe University of Frankfurt am Main, in Germany. His research work focus on solid state physics as well on the nanotechnology field, showing interest, for e.g., on understanding on how nanofabricated pinning landscapes affect the flux-flow instability velocity and current in superconducting materials.
Seminar abstract:
“A blank piece of paper is open for further patterning. It can be covered with words, symbols, or colors, breaking the symmetry of the blank paper and producing a sensory or abstract pattern. This pattern tells us a story, depicts an object, invokes a hidden feeling... . In this sense, patterning can generate a variety of new properties. In analogy to that, breaking the symmetry of superconducting films by nano-patterning results in novel properties unseen in pristine materials. This sets the stage for a new fascinating domain of science and engineering at the interface between superconductivity research and nanotechnology – Abrikosov fluxonics – which will be introduced in the present talk with a particular focus on microwave applications and metamaterials as miniature device.”
