表面声波是在固体表面传播的弹性波，其振幅衰减到固体内部。紧凑SAW器件的成熟制造，以及明确的共振频率，使SAW成为自旋电子学中操纵磁化状态的有吸引力的途径，所有这些都是通过磁致伸缩和磁弹性效应实现的。本文综述了声表面SAW器件的基本特性及其与薄膜磁化强度的共振外和共振内相互作用。我们描述了自己在这一研究领域的最新成果和密切相关的工作，并提供了我们的观点。
Surface acoustic waves (SAWs) are elastic waves propagating on the surface of solids with the amplitude decaying into the solid. The well-established fabrication of compact SAW devices, together with well-defined resonance frequencies, places SAWs as an attractive route to manipulate the magnetization states in spintronics, all of which is made possible by the magnetostriction and magnetoelastic effects. Here, we review the basic characteristics of SAW devices and their interaction out-of-resonance and in-resonance with the magnetization in thin films. We describe our own recent results in this research field and closely related works and provide our perspectives moving forward.
