Abstract

Ferromagnetic resonance (FMR)-induced voltaic effect and electrically modulated FMR absorption was observed in a Co x Nb y ( x = 81 , y = 19 ) soft ferromagnetic thin film by means of experimental technique based on electrically detected magnetic resonance (EDMR) and EM-FMR (electrical modulation of FMR). Our observations are interpreted as an evidence of electron-spin wave (magnon) coupling, in view of the previously reported case of multi-layers and domain walls. We suggest the experimental tools as an effective probe of spin-dependent transports in magnetic materials and devices.
