Abstract Vortex domain walls (DWs) are characterized by their chirality, an important property that needs to be controlled for the use of such walls in potential technological applications. In this work we explore a wire-ring structure in which we have alternate hard and soft magnetic materials. Our results evidence that, depending on the materials, it is possible to control the DW chirality when it goes through the ring section. Therefore, this system can be used as a device that controls domain wall chirality.

通过在具有线环形态的平面纳米结构中结合硬磁和软磁材料来控制畴壁手性

摘要 涡旋畴壁 (DW) 的特点是其手性，这是一种重要的特性，需要控制这种壁在潜在技术应用中的使用。在这项工作中，我们探索了一种线环结构，其中我们具有交替的硬磁和软磁材料。我们的结果证明，根据材料的不同，可以控制 DW 手性通过环部分时的手性。因此，该系统可用作控制畴壁手性的装置。
