Spin-Dependent Currents in Magnet/Normal Metal Based Magnetic Nanostructures

The spin transport through and near interfaces have been studied in magnet/normal metal based multilayer magnetic nanostructures in magneto-static and magneto-dynamic cases. Its features and accompanying effects, such as the magnetoresistance or the magnetic precession induced spin pumping and spin accumulation in adjacent normal metal are determined by the spin-dependent scattering on the interface. These effects are governed by the entire spin-coherent region that is limited in size by spin-flip relaxation processes and can be controlled by the spin-polarized current of different origin including the spin Hall effect. Conditions of realization of the mentioned spin currents in the multilayer magnetic nanostructures are studied.
