论文摘要
为了探索纳米厚的铁磁膜(超薄铁磁膜)的进一步可能性,我们研究了1 nm厚的CO膜的铁磁共振(FMR)。尽管未观察到在SIO2底物上生长的CO膜的FMR信号,但在CO下方插入3 nm厚的无定形TA缓冲层,这使得能够检测出显着的FMR信号,这归因于无相ta的平滑表面。该结果意味着在超薄铁磁膜中FMR的激发,这可以为控制超薄铁磁膜中的坚棒铺平道路。
To explore the further possibilities of nanometer-thick ferromagnetic films (ultrathin ferromagnetic films), we investigated the ferromagnetic resonance (FMR) of 1 nm-thick Co film. Whilst an FMR signal was not observed for the Co film grown on a SiO2 substrate, the insertion of a 3 nm-thick amorphous Ta buffer layer beneath the Co enabled the detection of a salient FMR signal, which was attributed to the smooth surface of the amorphous Ta. This result implies the excitation of FMR in an ultrathin ferromagnetic film, which can pave the way to controlling magnons in ultrathin ferromagnetic films.
