Flipse, J. (author), Dejene, F.K. (author), Wagenaar, D. (author), Bauer, G.E.W. (author), Ben Youssef, J. (author), Van Wees, B.J. (author) We report the observation of the spin Peltier effect (SPE) in the ferrimagnetic insulator yttrium iron garnet (YIG), i.e., a heat current generated by a spin current flowing through a platinum (Pt)|YIG interface. The effect can be explained by the spin transfer torque that transforms the spin current in the Pt into a magnon current in the YIG....
