论文摘要
静电门控限制并控制集成电路中电子的传输。磁子是磁性顺序的自旋波的量子，是有希望的替代信息载体，但很难登机。在这里，我们报告说，薄磁性膜顶部的超导条可以通过其对镁流浪场的磁反应完全反映木蛋白。诱导的大频移单上，在磁化强度的范围内阻止了镁化的传播。平行于磁化的两个超导门会产生宏伟的腔。 Gate Cooherent Magnons的选项为宏伟设备增加了功能，例如可重编程的逻辑设备，并增加了对其他自由度的耦合。
Electrostatic gating confines and controls the transport of electrons in integrated circuits. Magnons, the quanta of spin waves of the magnetic order, are promising alternative information carriers, but difficult to gate. Here we report that superconducting strips on top of thin magnetic films can totally reflect magnons by its diamagnetic response to the magnon stray fields. The induced large frequency shifts unidirectionally blocks the magnons propagating normal to the magnetization. Two superconducting gates parallel to the magnetization create a magnonic cavity. The option to gate coherent magnons adds functionalities to magnonic devices, such as reprogrammable logical devices and increased couplings to other degrees of freedom.
