(2024). Spin disorder control of topological spin texture. Nature Communications, 15(1), 3828. https://doi.org/10.1038/s41467-024-47715-5https://hdl.handle.net/1911/117923Stabilization of topological spin textures in layered magnets has the potential to drive the development of advanced low-dimensional spintronics devices. However, achieving reliable and flexible manipulation of the topological spin textures beyond skyrmion in a two-dimensional magnet system remains challenging. Here, we demonstrate the introduction of magnetic iron atoms between the van der Waals gap of a layered magnet, Fe3GaTe2, to modify local anisotropic magnetic interactions. Consequently, we present direct observations of the order-disorder skyrmion lattices transition. In addition, non-trivial topological solitons, such as skyrmioniums and skyrmion bags, are realized at room temperature. Our work highlights the influence of random spin control of non-trivial topological spin textures.engExcept where otherwise noted, this work is licensed under a Creative Commons Attribution (CC BY) license.
