Abstract
The macroscopic description of spin-dependent electronic transport in magnetic-layered structures is extended by including the effects due to spin-flip scattering at the interfaces between magnetic and nonmagnetic layers. Such processes lead to spin-memory losses at the interfaces and therefore play a significant role in the giant magnetoresistance and current-induced magnetic switching phenomena. Interface spin-flip scattering significantly modifies the distribution of spin currents and spin accumulation in the vicinity of the interface. Two semi-infinite systems in direct contact, as well as magnetic/nonmagnetic (F∕N) sandwiches and superlattices, are considered for both parallel and antiparallel magnetic configurations.
