Dr. Paolo Perna
Paolo Perna obtained his BCs + MCs in theoretical Physics on 2003 from the University Federico II in Naples (Italy) and then moved to the experimental research. On 2008, he obtained two PhD titles in Physics: Condensed Matter and Devices from the University of Caen Basse-Normandie (France) and in Mechanical Engineering (Material Science) from the University of Cassino (Italy). During his PhD, he has been granted of an individual exchange fellowship from the European Science Foundation (2006). After a postdoctoral research contract at the CNR-SPIN in Naples (Italy), on 2009 he joined the Nanomagne- tism’s group at IMDEA Nanoscience within the Marie Curie AMAROUT fellowship program and, on 2011 he obtained a Juan de la Cierva fellowship. Actually, PP is researcher at IMDEA Nanoscience leading the SpinOrbitronic group. He is responsible of the Advanced Magneto Optics Lab and of the Sputtering facility of the Multi-purpose UHV growth/spectroscopy Lab.
His research activities cover both fabrication and characterization of magnetic and non-magnetic systems focusing on their fundamental properties and potential technological applications. In particular, his research is mostly dedicated to the understanding and realization of novel spintronics and spinorbitronic devices by employing materials with tailored interface functionalities.
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 micros- copy, magnetic holography imaging.
