本文报道了一种基于自旋波干涉的自旋波开关的实验数据。该开关是一个三端器件，其中源极和漏极之间的自旋波传播由控制自旋波信号调制。原型是基于Y_3Fe_2（FeO_4）（3）薄膜的微米级器件。输出特性示出了作为源极和漏极自旋波信号之间的相位差的函数的输出自旋波信号的振荡。在室温下，样机的通断比超过20 dB。利用相位除了幅度的信息编码提供了一个创新的途径，多状态逻辑电路。讨论了自旋波开关的优缺点。(C)2018年作者。
In this work, experimental data on a spin wave switch based on spin wave interference is reported. The switch is a three terminal device where spin wave propagation between the source and the drain is modulated by the control spin wave signal. The prototype is a micrometer scale device based on Y3Fe2(FeO4)(3) film. The output characteristics show the oscillation of the output spin wave signal as a function of the phase difference between the source and the drain spin wave signals. The On/ Off ratio of the prototype exceeds 20 dB at room temperature. The utilization of phase in addition to amplitude for information encoding offers an innovative route towards multi-state logic circuits. The advantages and shortcomings of spin wave switches are also discussed. (C) 2018 Author(s).
