实现了一种基于宽度调制动态磁振子晶体的电流控制自旋波逻辑门。该器件利用了由单晶钇铁石榴石薄膜和两条连接到薄膜表面的导线制成的自旋波波导。将电流施加到导线上提供了一种用于动态控制波导的有效几何形状的手段，并导致磁振子带隙的抑制。磁振子晶体作为一个与逻辑门的性能被证明。(C)2015 AIP Publishing LLC.
An electric current controlled spin-wave logic gate based on a width-modulated dynamic magnonic crystal is realized. The device utilizes a spin-wave waveguide fabricated from a single-crystal Yttrium Iron Garnet film and two conducting wires attached to the film surface. Application of electric currents to the wires provides a means for dynamic control of the effective geometry of waveguide and results in a suppression of the magnonic band gap. The performance of the magnonic crystal as an AND logic gate is demonstrated. (C) 2015 AIP Publishing LLC.
