磁和声激励之间的相互作用最近激发了许多跨学科的研究，从基础物理到电路实现。具体而言，通过磁致弹性耦合实现的它们的相干相互转换的探索开辟了一个新的操场，结合应变电子学和自旋电子学，并提供了一个独特的平台，用于建立芯片上的相干信息处理网络与小型化的磁和声学器件。在这方面，我们将重点介绍磁振子-声子耦合动力学系统的最新进展，包括材料，电路，成像和新物理。特别是，我们强调的独特功能，如非互易声波传播和磁振子和声子之间的强耦合的磁性薄膜系统，这提供了一个平台，他们的相干操纵和转导。我们也将回顾声表面波共振器在相干量子转换中的前沿，并讨论如何将这种新颖的声电路设计应用于微波自旋电子学。
The interaction between magnetic and acoustic excitations has recently inspired many interdisciplinary studies ranging from fundamental physics to circuit implementation. Specifically, the exploration of their coherent interconversion enabled via the magnetoelastic coupling opens a new playground combining straintronics and spintronics and provides a unique platform for building up on-chip coherent information processing networks with miniaturized magnonic and acoustic devices. In this Perspective, we will focus on the recent progress of magnon-phonon coupled dynamic systems, including materials, circuits, imaging, and new physics. In particular, we highlight the unique features such as nonreciprocal acoustic wave propagation and strong coupling between magnons and phonons in magnetic thin-film systems, which provide a platform for their coherent manipulation and transduction. We will also review the frontiers of surface acoustic wave resonators in coherent quantum transduction and discuss how the novel acoustic circuit design can be applied in microwave spintronics.
