This page shows details on the project. The primary projects are displayed together with a list of sub-projects.
|Project description:||Spintronic GMR and TMR nanopillars (lateral size (150nm) for current induced magnetization switching (CIMS) studies will be prepared and analyzed. GMR nanopillars will be prepared by UHV deposition and nanoparticles lift off lithography and electron beam lithography (EBL). Novel TMR nanopillars with embedded magnetic nanoparticles will be prepared by UHV evaporation, LB nanoparticles deposition and EBL. Magnetic configurations of nanopillars will be studied by scanning MOKE microscope. We will study correlation between nanopillar structure, interface roughness (vertical and lateral correlations) and Neel ferromagnetic coupling with magnetic and CIMS behavior with the aim to lower the switching current. Magnetization behaviour in situ by its spin polarized current switching will be analyzed by simultaneous simultaneous the R (dynamic) vs. current and Kerr rotation vs. H experiments.|
