Magnetization dynamics allows spin pumping in condensed matters, and detection of electromotive forces from the condensed matters due to their inverse spin Hall effect provides proof of spin injection. Ni80Fe20 has been widely used as a spin source, but no light was shed on its intrinsic inverse spin Hall effect (ISHE) although Ni80Fe20 possesses non-negligible spin-orbit interaction, which induces anisotropic magnetoresistance. Here, we report on an observation of electromotive forces from Ni80Fe20 due to the intrinsic inverse spin Hall effect. Furthermore, the electromotive forces in Ni80Fe20 are found to be controllable by an appropriate choice of connected materials.
