利用基于电检测磁共振(EDMR)和EM-FMR(电调制FMR)的实验技术，在Co{subx}Nb{suby}(x=81，y=19)软铁磁薄膜中观察到了铁磁共振(FMR)诱导的伏特效应和电调制FMR吸收.考虑到以前报道的多层和磁畴壁的情况，我们的观察被解释为电子-自旋波(磁振子)耦合的证据。我们建议将该实验工具作为研究磁性材料和器件中与自旋相关的输运的有效探针。
Ferromagnetic resonance (FMR)-induced voltaic effect and electrically modulated FMR absorption was observed in a Co{sub x}Nb{sub 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.
