Observation of transverse spin Nernst magnetoresistance induced by thermal spin current in ferromagnet/non-magnet bilayers

Abstract

Pure spin current generated thermally in nonmagnetic materials known as spin Nernst effect has not been demonstrated experimentally. Here, the authors report the observation of spin Nernst effect by studying the thermally-induced transverse magnetoresistance in ferromagnet/non-magnet heavy metal bilayers
