我们提出了一种在耦合纳米线系统中没有直流电应用的情况下驱动多个畴壁的方法。畴壁由远程耦合和来自畴壁压缩的交换排斥力的组合驱动。磁畴壁被压缩，因为它们由于具有相似的拓扑电荷而无法相互湮灭。压缩存在于后续的畴壁之间，这使得它们能够在耦合的纳米线系统中作为一个组被驱动。
We present a method to drive multiple domain walls in the absence of direct current application in a coupled nanowire system. The domain walls were driven by a combination of remote coupling and exchange repulsion force from the domain wall compressions. The domain walls were compressed as they were unable to annihilate each other due to having similar topological charges. The compressions are present between the subsequent domain walls, which allow them to be driven as a group in the coupled nanowire system.
