摘要
Measurements of the spin heat accumulation at the ferromagnetic/non-magnetic interface in nanopillar spin valves show that spin-up and spin-down electrons have different temperatures. This observation is important for the design of magnetic thermal switches and the study of inelastic spin scattering.
