Abstract

We report the electromotive force (EMF) properties generated in 3d-transition ferromagnetic metal (FM = Fe, Co, and Ni80Fe20) films themselves under their ferromagnetic resonance (FMR). For Fe and Co films, the EMF due to the anomalous-Hall effect is dominantly generated under their FMR. Meanwhile, for a Ni80Fe20 film, the EMF due to the inverse spin-Hall effect in the Ni80Fe20 film itself under the FMR is mainly generated. This tendency is qualitatively explained with differences of the spin polarization, the spin Hall conductivity, the anomalous Hall conductivity, the magnetization saturation, and the resistivity of the FM films.
