Abstract

We report Y3Fe5O12 thickness dependence of spin pumping, spin current generation from magnetization dynamics, in magnetic insulator Y3Fe5O12/metal Pt bilayer films. We prepared different thickness Y3Fe5O12 films by the metal-organic decomposition method and measured the electromotive force due to the inverse spin Hall effect induced by the spin pumping in Y 3Fe5O12/Pt films. We found that spin-mixing conductance, or spin-pumping efficiency, Y3Fe5O 12/Pt films constant for the different thickness is almost same in various Y3Fe5O12 thickness. This result is consistent with the prediction of the spin pumping; the spin-pumping efficiency is determined by the exchange interaction at the Y3Fe 5O12/Pt interface.
