论文摘要
使用自旋波来传输和处理信息的镁质是低功率数据处理的有希望的场所。主要挑战之一是对自旋波传播路径的局部控制。在这里，我们通过利用高度灵活的可重构性和人工旋转冰系统的可重复性来介绍可写的镁质的概念。使用微磁模拟，我们表明可以在人造链式旋转冰冰的基础的铁磁性薄膜中实现全球可切换的自旋波传播和本地旋转波纳米通道。可重新配置的可重写的磁元能由可重新配置的自旋波纳米通道纳米通道提供了一个独特的设置，可设计可编程的磁通电路和逻辑设备，以实现超低功率应用。
Magnonics, which employs spin-waves to transmit and process information, is a promising venue for low-power data processing. One of the major challenges is the local control of the spin-wave propagation path. Here, we introduce the concept of writable magnonics by taking advantage of the highly flexible reconfigurability and rewritability of artificial spin ice systems. Using micromagnetic simulations, we show that globally switchable spin-wave propagation and the locally writable spin-wave nanochannels can be realized in a ferromagnetic thin film underlying an artificial pinwheel spin ice. The rewritable magnonics enabled by reconfigurable spin wave nanochannels provides a unique setting to design programmable magnonic circuits and logic devices for ultra-low power applications.
