Spin-current absorption by inhomogeneous spin-orbit coupling
arXiv:1204.2189 · doi:10.1103/PhysRevB.86.155210
Abstract
We investigate the spin-current absorption induced by an inhomogeneous spin-orbit coupling due to impurities in metals. We consider the system with spin currents driven by the electric field or the spin accumulation. The resulting diffusive spin currents, including the gradient of the spin-orbit coupling strength, indicate the spin-current absorption at the interface, which is exemplified with experimentally relevant setups.
