Heikkilä, T.T. (author), Hatami, M. (author), Bauer, G.E.W. (author)We study the concept of spin heat accumulation in excited spin valves, more precisely the effective electron temperature that may become spin dependent, both in linear response and far from equilibrium. A temperature or voltage gradient create nonequilibrium energy distributions of the two spin ensembles in the normal-metal spacer, which...journal article 2010
