Abstract

Exchange interaction between conduction electrons and magnetic moments at magnetic interfaces leads to mutual conversion between spin current and magnon current. We introduce a concept of spin convertance which quantitatively measures magnon current induced by spin accumulation and spin current created by magnon accumulation at a magnetic interface. We predict several phenomena on charge and spin drag across a magnetic insulator spacer for a few layered structures.
