Abstract
A magnetic vortex is a structure with a polarized core surrounded by an in-plane spin swirl and was first reported in easy-plane disks. Here, we explore the effects of the disk thickness, temperature, and out-of-plane field on the magnetic vortex stabilization and core reversals in Kagome uniaxial ferromagnetic Fe3Sn2 disks. Magnetic ground domains in Fe3Sn2 disks turn from stripes to vortices after decreasing the disk thickness or temperature as the easy-plane anisotropy wins the competition with the uniaxial magnetocrystalline anisotropy. Topological transformations from charge Q=−1/2 vortices at a zero field to Q=−1 skyrmion-like configurations at a high out-of-plane field were identified in cooperation with micromagnetic simulations. Thus, our results promote future vortex-based spintronic applications.
