论文摘要

Skyrmions和Bimerons是通用的拓扑旋转纹理,可以用作经典和量子计算的信息位。孤立的天空和Bimerons之间的转换是基于多个不同拓扑位计算体系结构的重要操作。在这里,我们报告了通过利用电流引起的奥斯特场和温度引起的垂直磁各向异性变化来创建孤立的天际及其随后转化向比门龙的转化。 Skyrmions和Bimerons之间的转换是可逆的,它由当前幅度和扫描方向控制。 Skyrmions和Bimeron都可以通过Skyrmion-Bimeron转换和磁化切换在同一系统中创建。变形的天空气泡和手性迷宫域被发现为非平凡的中间过渡状态。我们的结果可能提供了一种独特的方法,可以使用同一系统中不同类型的拓扑旋转纹理构建高级信息处理设备。

Skyrmions and bimerons are versatile topological spin textures that can be used as information bits for both classical and quantum computing. The transformation between isolated skyrmions and bimerons is an essential operation for computing architecture based on multiple different topological bits. Here we report the creation of isolated skyrmions and their subsequent transformation to bimerons by harnessing the electric current-induced Oersted field and temperature-induced perpendicular magnetic anisotropy variation. The transformation between skyrmions and bimerons is reversible, which is controlled by the current amplitude and scanning direction. Both skyrmions and bimerons can be created in the same system through the skyrmion-bimeron transformation and magnetization switching. Deformed skyrmion bubbles and chiral labyrinth domains are found as nontrivial intermediate transition states. Our results may provide a unique way for building advanced information-processing devices using different types of topological spin textures in the same system.
