利用压电-磁混合系统，我们已经产生了由磁弹性介导的大幅度磁化波，磁化方向的变化高达25度。我们提出了在镍薄膜中对驻留和传播的不同波长的声磁波的直接成像和量化，在长达几毫米的距离上。
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.
