The spin mixing conductance at Au/BiY 2Fe 5O 12 and Pt/BiY 2Fe 5O 12 interfaces was electrically determined using the inverse spin Hall effect (ISHE) and the spin pumping. By measuring the electromotive force due to the ISHE and the ferromagnetic resonance spectra, we evaluated the magnitude of the generated spin currents and the magnetization-precession trajectory. The spin mixing conductance was estimated as 1.82 × 10 18m -2 for the Pt/BiY 2Fe 5O 12 film, and as 2.21 × 10 18m -2 for the Au/BiY 2Fe 5O 12 film, demonstrating efficient spin exchange at these metal/insulator interfaces.
