Research Topic: Exploring Correlated Spin Systems in Quantum Materials with Neutron Scattering
My work delves into low-temperature strongly correlated electron systems, with an emphasis on quantum materials such as magneto-dielectric materials, single-ion magnets, single-chain magnets, and quantum spin liquids. During my PhD, I have gained expertise in synthesizing novel metal oxides and analyzing their crystallographic structures using XRD. I have hands-on experience with advanced neutron scattering techniques and data analysis, including neutron powder diffraction (NPD) to explore ground-state magnetic structures and inelastic neutron scattering (INS) to study minute excitations such as magnons, phonons, and crystal electric field (CEF) interactions, supported by MATLAB-based theoretical modeling.
Additionally, I have also worked on photocatalytic systems and a basic understanding of TEM, XPS, and Raman spectroscopy, enabling work with diverse materials. In the future, I aim to expand my neutron scattering expertise to other systems such as biological soft matter, MOFs, thin-film nanostructures, and single crystals. My research is driven by a curiosity about complex phenomena and a commitment to advancing materials science.

Research Topic: Strongly correlated d-f coupled magnetoelectric systems
I am working on strongly correlated electron systems. These materials are particularly interesting, owing to their unique and complex magnetic behaviors. My PhD work is focused on designing ruthenium (4d) based specialized magnetoelectric/multiferroic systems and investigating their magnetic and ME properties by adjusting the d-f coupling by introducing rare-earth ions (f-orbitals). The 4d-4f coupled systems create a playground for discovering new and unexpected phenomena. My main motivation is to explore the underlying physics of this correlated quantum materials through neutron diffraction (ND) and Inelastic Neutron Scattering investigation. I'm able to probe deep into these materials, uncovering details about their magnetic structures and how they change under different conditions as neutron is highly sensitive to small lattice distortions and local magnetic interactions. The INS depicts a clear picture about its spin-excitation and spin-phonon coupling. I have expertise in analysing and modelling ND and INS data using different software , e.g., FullProf, SARAH, SpinW, DAVE, and Mantid. In addition I am learning pair-distribution function analysis to investigate the small local distortion in lattice in this correlated quantum materials.

Research Topic: Multifunctional Materials-Perovskite Nanocrystals and Bulk Oxide
My research is centered on the development of multifunctional materials with applications in green and clean energy technologies. Driven by the urgency to mitigate global warming, I focus primarily on synthesizing highly efficient multifunctional materials. One is magnetocaloric materials which can be used as eco-friendly magnetic refrigerator. My additional motivation is to contribute to Carbon Zero initiatives by synthesizing efficient ambient photocatalysts that can convert carbon dioxide into valuable products like ethanol, methanol, and methane. I have expertise in sample synthesis employing various method. I have synthesized new oxide using solid-state-reaction method. I have grown single crystal using flux growth method. I have experience in optical floating zone method. In addition, I also grow nanocrystals using hot injection and solvothermal method for photocatalysis. To ensure the phase purity and to analyze the physical properties of these materials, I utilize a range of advanced analytical techniques. X-ray diffraction (XRD) is employed for crystallographic studies and phase identification, while UV-Visible (UV-Vis) spectroscopy is used for band gap determination. Thermal analysis, such as heat capacity measurements, provides insights into thermodynamic properties. For morphological and elemental analysis, I use Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). Magnetic properties are thoroughly examined through magnetization versus field (M-H) and temperature (M-T) studies, as well as powder neutron diffraction (PND), which helps uncover the competing interactions and underlying physics in long-range magnetic ordering. Additionally, my research extends into the exploration of advanced quantum materials, including quantum spin liquids, spin chain systems, and two-dimensional layered honeycomb magnets with Kiteav interaction, and Kagome staircase systems. My plan is to gain expertise in Inelastic neutron scattering (INS) to probe magnetic excitations in quantum spin liquid systems.

Research Topic: Microscopic Investigation of Correlated Quantum Materials
I am working on Quantum Materials using X-ray diffraction (HR-XRD), X-ray absorption spectroscopy (XAS) and Muon spin relaxation/rotation spectroscopy (muSR). I use high-resolution synchrotron XRD and XAS (XANES, EXAFS) to understand the minute details of crystal structure and elemental information. For the understanding of complex spin dynamics of our systems, I mostly use muSR, which is a great tool to probe local-level spin dynamics in materials. One of my motivations is to explore the quantum criticality in exotic magnetic materials. In addition, with synchrotron studies, I have good exposure on sample synthesis using solid-state-reaction method. I also plan to learn some complementary techniques, like X-ray Photoelectron Spectroscopy (XPS), Raman Spectroscopy, and Inelastic Neutron Scattering (INS). I have expertise in using some software like FullProf, Mantid, WiMDA, Origin, Athena, Artemis, etc.
