Abstract
Using hybrid piezoelectric-magnetic systems we have generated large amplitude magnetization waves mediated by magnetoelasticity with up to 25 degrees variation in the magnetization orientation. We present direct imaging and quantification of both standing and propagating acoustomagnetic waves with different wavelengths, over large distances up to several millimeters in a nickel thin film.
摘要
利用混合压电-磁系统，我们通过磁弹效应产生了大振幅的磁化波，其磁化方向的变化幅度高达 25 度。我们在镍薄膜中直接成像并量化了不同波长的驻波和传播声波，其传播距离长达数毫米。
