摘要

本文对弹性兰姆波、剪切水平波和自旋波在受限纳米铁磁条中的耦合进行了数值研究。在这里，我们报告了兰姆波、剪切水平波和自旋波之间的非互反相互作用。我们的研究结果表明，弹性波的传播具有角相关的非倒易特性，这是由磁弹性耦合引起的。这项工作为自旋电子应用提供了对受限磁弹性波的进一步理解，为实现非互易混合磁振子器件提供了另一种方法。

Nonreciprocal interaction between Lamb waves, shear horizontal waves and spin waves at confined ferromagnetic heterojunction

We present a numerical study on the coupling between elastic Lamb waves, shear horizontal waves, and spin waves in a confined nanoscale ferromagnetic strip. Here, we report the nonreciprocal interactions between Lamb waves, shear horizontal waves, and spin waves. Our findings indicate that the elastic wave propagation has angular-dependent nonreciprocal characteristics, resulting from the magnetoelastic couplings. This work offers a further understanding of confined magnetoelastic waves for spintronic applications, providing an alternative approach to the realization of nonreciprocal hybrid magnonic devices.

期刊介绍： The Journal of Magnetism and Magnetic Materials provides an important forum for the disclosure and discussion of original contributions covering the whole spectrum of topics, from basic magnetism to the technology and applications of magnetic materials. The journal encourages greater interaction between the basic and applied sub-disciplines of magnetism with comprehensive review articles, in addition to full-length contributions. In addition, other categories of contributions are welcome, including Critical Focused issues, Current Perspectives and Outreach to the General Public. Main Categories: Full-length articles: Technically original research documents that report results of value to the communities that comprise the journal audience. The link between chemical, structural and microstructural properties on the one hand and magnetic properties on the other hand are encouraged. In addition to general topics covering all areas of magnetism and magnetic materials, the full-length articles also include three sub-sections, focusing on Nanomagnetism, Spintronics and Applications. The sub-section on Nanomagnetism contains articles on magnetic nanoparticles, nanowires, thin films, 2D materials and other nanoscale magnetic materials and their applications. The sub-section on Spintronics contains articles on magnetoresistance, magnetoimpedance, magneto-optical phenomena, Micro-Electro-Mechanical Systems (MEMS), and other topics related to spin current control and magneto-transport phenomena. The sub-section on Applications display papers that focus on applications of magnetic materials. The applications need to show a connection to magnetism. Review articles: Review articles organize, clarify, and summarize existing major works in the areas covered by the Journal and provide comprehensive citations to the full spectrum of relevant literature.
