Detection of spin-wave spin current in a magnetic insulator

Kajiwara, Yosuke*; Takahashi, Saburo*; Maekawa, Sadamichi; Saito, Eiji*

Conduction electron can carry a flow spin angular momentum, a spin current. This paper describes another type of spin current: a spin current carried by spin waves. Some types of spin waves can carry a spin current, which can propagate both in insulators and metals. These two types of spin currents were found to exchange each other at a Pt/Y $_{3}$ Fe $_{5}$ O $_{12}$ interface.
