摘要:

为了进一步探索纳米厚铁磁薄膜的可能性,我们研究了1 nm厚Co薄膜的铁磁共振(FMR)。虽然FMR信号没有观察到的Co膜生长在SiO2基板上,插入的3 nm厚的非晶Ta缓冲层下面的Co能够检测到一个突出的FMR信号,这是由于非晶Ta的光滑表面。这一结果暗示了铁磁薄膜中FMR的激发,为控制铁磁薄膜中的磁振子奠定了基础。

英文摘要:

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.
