Current-Induced Reversible Split of Elliptically Distorted Skyrmions in Geometrically Confined Fe₃ Sn₂ Nanotrack.

ABSTRACT: Skyrmions are swirling spin textures with topological characters promising for future spintronic applications. Skyrmionic devices typically rely on the electrical manipulation of skyrmions with a circular shape. However, manipulating elliptically distorted skyrmions can lead to numerous exotic magneto-electrical functions distinct from those of conventional circular skyrmions, significantly broadening the capability to design innovative spintronic devices. Despite the promising potential, its experimental realization so far remains elusive. In this study, the current-driven dynamics of the elliptically distorted skyrmions in geometrically confined magnet Fe₃ Sn₂ is experimentally explored. This study finds that the elliptical skyrmions can reversibly split into smalle
