Spin current injection and spin accumulation near a ferromagnetic insulator(FI)/nonmagnetic metal (NM) bilayer film under a thermal gradient isinvestigated theoretically. Using the Fermi golden rule and the Boltzmannequations, we find that FI and NM can exchange spins via interfacialelectron-magnon scattering because of the imbalance between magnon emission andabsorption caused by either non-equilibrium distribution of magnons ornon-equilibrium between magnons and electrons. A temperature gradient in FIand/or a temperature difference across the FI/NM interface generates a spincurrent which carries angular momenta parallel to the magnetization of FI fromthe hotter side to the colder one. Interestingly, the spin current induced by atemperature gradient in NM is negligibly small due to the nonmagnetic nature ofthe non-equilibrium electron distributions. The results agree well with allexisting experiments.
