Research Abstract

The spin Seebeck effect refers to the generation of a spin voltage caused by a temperature gradient in a ferromagnet, which enables the thermal injection of spin currents from the ferromagnet into an adjacent nonmagnetic metal over a macroscopic scale of several millimeters. The inverse spin Hall effect converts the injected spin current into a transverse charge voltage, thereby producing electromotive force as in the conventional charge Seebeck device. The basic mechanism of the spin Seebeck effect has been theoretically investigated in this project, and it has been shown that non-equilibrium magnons and phonons play crucial roles in the spin Seebeck effect.
