Abstract The features of spin wave processes in a layered structure based on two magnonic crystals (MC-1 and MC-2) separated by a dielectric layer have been studied theoretically and experimentally at different levels of input power. The theoretical model has been developed for the cases of magnetic field oriented in-plane and out-of-plane to MC surfaces in order to identify the mechanisms of nonlinear interactions. Two types of nonlinear switching are implemented in the structure MC-1/MC-2 with increasing input power. Depending on parameters of the structure the input signal can exit from three (“double nonlinear switching”) or two (“single nonlinear switching”) outputs. This feature allows to consider MC-1/MC-2 structure as a basic element in a multifunctional device for the spatial separation of signals with different power levels.

基于磁子晶体的分层结构非线性自旋波开关

摘要 已经在理论和实验上研究了在不同输入功率水平下基于由介电层分隔的两个磁子晶体（MC-1 和 MC-2）的分层结构中的自旋波过程的特征。已针对磁场在面内和面外定向到 MC 表面的情况开发了理论模型，以识别非线性相互作用的机制。随着输入功率的增加，在结构 MC-1/MC-2 中实现了两种非线性切换。根据结构的参数，输入信号可以从三个（“双非线性开关”）或两个（“单非线性开关”）输出输出。此功能允许将 MC-1/MC-2 结构视为多功能设备中的基本元素，用于空间分离不同功率电平的信号。
