Abstract

Recent theories of spin-current-induced magnetization reversal are formulated in terms of a spin-mixing conductance Gmix. We evaluate Gmix from first principles for a number of (dis)ordered interfaces between magnetic and nonmagnetic materials. We predict that the magnetization direction of a ferromagnetic insulator or of one side of a tunnel junction in a multiterminal device can be switched even though a negligible charge current is passed.
