In this paper, we have investigated spin currents generated by the spin pumping in ferromagnetic metal/Pt and ferromagnetic insulator/Pt bilayer films using the inverse spin-Hall effect (ISHE). We found that the magnitude of the electric voltage due to the ISHE is well reproduced by a calculation based on the model of the spin pumping not only in transition magnetic metal/Pt bilayer films, but also in polycrystalline magnetic insulators BiY 2 Fe 5O 12 / Pt and Y 3 Fe 5O 12 / Pt. This result will show a guideline for creating a spin current in a wide range of materials.
