Spin-Seebeck Effect in III-V Based Semiconductors

ORAL

Abstract

The spin-Seebeck effect has now been observed in metals$^{1}$ (NiFe), semiconductors$^{2}$ (GaMnAs), and insulators$^{3}$ (YIG). It consists of a thermally generated spin distribution that is phonon driven. Here we extend our measurements of the spin-Seebeck effect to other group III-V based magnetic semiconductors and present measurements of conventional thermomagnetic and galvanomagnetic properties as well as the spin-Seebeck effect.
