In this study, switching of the spin-wave propagation was investigated using an yttrium iron garnet (YIG) waveguide. A dynamic magnonic crystal (DMC) was designed to control the non-reciprocal surface spin waves. The DMC controlled the periodic modulation field on the YIG film and caused a strong Bragg reflection on the surface spin waves. The maximum effect of Bragg reflection was analyzed by the wavelet to be 95% of its intensity. The spin-wave switching by the DMC will be a promising method of carrier-flow control for constructing the integrated magnonic circuits.

使用动态磁子晶体的自旋波切换
在这项研究中,使用钇铁石榴石 (YIG) 波导研究了自旋波传播的切换。设计了动态磁子晶体 (DMC) 来控制非互易表面自旋波。DMC 控制 YIG 薄膜上的周期性调制场,并在表面自旋波上引起强烈的布拉格反射。小波分析布拉格反射的最大影响为其强度的 95%。DMC 的自旋波切换将是一种很有前途的载流控制方法,用于构建集成磁子电路。
