Abstract

Magnetic skyrmions are emerging as promising candidates for next-generation information technologies, while the realization of scalable skyrmion lattices with tailored configurations is essential for advancing fundamental skyrmion physics and developing future applications. Here we achieved the controllable generation and regulation of a large-area, highly oriented skyrmion track array (STA) in ferromagnet Fe3GaTe2 using a vector-magnetic-field manipulation technique. The orientation and ordering of STA, along with the types and density of skyrmions, are precisely controlled by modulating parameters during the manipulation. The critical roles of in-plane magnetic fields and Dzyaloshinskii-Moriya interaction in STA generation is further confirmed by micromagnetic simulation. Our findings develop a strategy for engineering large-area and highly oriented skyrmion configurations, offering a new pathway for the future application of next-generation spintronic and information technologies.

大块Fe3GaTe2的可控高定向Skyrmion跟踪阵列

磁性skyrmions正在成为下一代信息技术的有前途的候选者，而实现具有定制配置的可扩展skyrmions晶格对于推进基础skyrmions物理和开发未来应用至关重要。本文采用矢量磁场操纵技术，在Fe3GaTe2铁磁材料中实现了大面积、高定向skyrmion磁道阵列（STA）的可控生成和调控。在操作过程中，通过调制参数精确控制STA的方向和顺序，以及skyrmions的类型和密度。微磁模拟进一步证实了面内磁场和Dzyaloshinskii-Moriya相互作用在STA生成中的关键作用。我们的研究结果为设计大面积和高度定向的skyrmion配置提供了一种策略，为下一代自旋电子和信息技术的未来应用提供了新的途径。2025年由美国物理学会出版
