Abstract of the talk of Dr. Alex Matos-Abiague: The symmetry and origin of spin-orbit coupling (SOC) fields at semiconductor and hybrid (ferromagnet/semiconductor) interfaces is investigated. It is shown that the specific angular dependence of the tunneling anisotropic magnetoresistance (TAMR) in magnetic tunnel junctions is determined by the symmetry of the SOC fields. Tunnel junctions with different configurations regarding composition, growth direction, and/or strain are discussed. Some theoretical predictions of the angular dependence of the TAMR and comparison with available experimental data are presented. The current-driven spin torque induced by the SOC in a single ferromagnetic layer is also addressed. In particular, we show how the current-flow direction can be used as a control parameter for generating magnetization switching and dynamics. Finally, some manifestations of the SOC on many-body phenomena in 2D semiconductor systems are briefly discussed with emphasis on the anisotropic plasmon filtering effect and the beating of Friedel oscillations.
