Abstract :
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/Y3Fe5O12 interface.
