SPIN ORBITRONICS GROUP

Dr. Paolo Perna

The SpinOrbitronics Group at IMDEA Nanoscience is part of the Nanomagnetism Research program. The group focuses the interests on solid state physics and material science of low dimensional magnetic materials, covering epitaxial growth, surface/interface and magnetotransport characterization, nanofabrication.

In particular:

  • Disentangling magnetoresistance responses in magnetic nanostructures: magnetization reversal vs. spin-dependent transport; magnetic anisotropies (in-plane vs. perpendicular); Magnetoresistive effects: AMR, GMR, CMR, Spin Hall effects; Symmetries and asymmetries of Spin-Orbit effects.
  • Development of new hybrid (inorganic-organic) magnetic nanostructures: growth of artificial magnetic nanostructures; molecular spintronic and graphene-based magnetic nanostructures; exchange bias, spin valves, tunnel junctions, perovskite oxides;
  • Functional oxide interfaces: high-k dielectric, half-metallic, ferroelectric and multiferroic perovskites.
  • Polarization dependent element-resolved x-ray spectroscopy and microscopy studies: X-ray magnetic circular/linear dichroism, XMCD/XMLD, & resonant magnetic reflectivity, XRMR X-ray photoemission electron microscopy, magnetic holography imaging.
