通过研究信号在环形磁体链中的传播，证明了场耦合纳米磁逻辑（NML）系统中的信息传输。磁铁布局，信号注入时间，和所需的时钟字段的设计标准。磁体之间的强相互作用通过模拟估计，并通过磁滞曲线测量验证。通过磁力显微镜测量，特别是具有平行磁化的亚稳态磁体对的传播，证实了磁线中的信号传输。场耦合磁逻辑器件首次成功运行了数百个时钟周期。大量的研究验证了场耦合NML系统中垂直磁介质信息传输的可靠性和鲁棒性。
The information transport in field-coupled nanomagnetic logic (NML) systems is demonstrated by investigating signal propagation in a circular chain of magnets. Design criteria for the magnet layout, signal injection timing, and the required clocking field are presented. The strong interaction between the magnets is estimated by simulations and verified by hysteresis curve measurements. Signal transmission in the magnetic wire is confirmed by magnetic force microscopy measurements, especially the propagation of a metastable pair of magnets with parallel magnetization. For the first time, a field-coupled magnetic logic device is successfully operated for hundreds of clocking cycles. Extensive studies verify the reliability and robustness of information transport in field-coupled NML systems from perpendicular magnetic media.
