Abstract:

This project addresses innovative fundamental physics of spin and charge transport in Magnetic Tunnel Junctions (MTJ) employing half-metallic ferromagnetic (FM) electrodes with low Gilbert damping and tailor their magneto-transport properties and application potential. The dependence of magnetic anisotropy on the film thickness, composition and interface symmetries will be investigated, aiming towards perpendicular magnetic anisotropy (PMA). Specific MTJ architectures with engineered characteristics, patterned in micrometric and nanometric size pillars, will be elaborated using interface chemical tuning and inserting symmetry dependent quantum wells. They will be characterized by local near field techniques and by temperature and field-dependent tunneling spectroscopy. We focus on understanding the depolarizing mechanisms, lose and recovery of half-metallicity by symmetry filtering effects. The transport mechanisms will be analyzed from correlated static DC and dynamic (noise) transport spectroscopy in variable temperature. The spin torque related noise enhancement in low Gilbert damping FM electrodes based MTJs will be addressed. The influence of electronic structure and magnetism of interfaces on spin and charge transport, the interplay between spin-orbit coupling, PMA, and anisotropic tunneling magnetoresistive effects will be investigated. The experimental studies will be accompanied by theoretical modeling by combining ab-initio, analytical and numerical approaches.
