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.
