Summary: This research project focuses on spin-polarized transport phenomena in artificial magnetic nanostructures. We will study, on one hand, the magneto-transport properties of ferromagnetic thin films that are components of magnetoresistive devices. On the other hand, we will design and fabricate magnetoresistive devices based on (i) metallic oxides and (ii) III-V semiconductors. The aim of our investigation resides in the exploration of the contributions of ferromagnetic/non-magnetic interfaces and bulk layers to the spin-dependent scattering in both systems. The study of the magnetotransport properties of the samples will be done by measuring magnetoresistance, Hall effect and I-V curves. The project includes the growth of the oxides nanostructures and its structural and chemical characterization. The tunnel junctions and the others magnetoresistive devices will be nanostructured using lithographical techniques. A fundamental aspect of this project is the student education at the graduate and undergraduate levels in this area of research.
