Spin waves, spin currents and spin seebeck effect

Abstract

The spin Seebeck effect is now established as a universal aspect of ferromagnets that enables thermal injection of spin currents from a ferromagnet into attached nonmagnetic metals over macroscopic scale of several millimeters. We show that the spin-wave degrees of freedom play a crucial role in the spin Seebeck effect. © Springer-Verlag Berlin Heidelberg 2013.
