Stabilization and positioning of a spin vortex in nanostructured ferromagnetic thin films

Spin vortex is a very common structure in ferromagnetic thin films, but it can be easily shifted by an in-plane applied field. The paper demonstrates that the vortex can be positioned over certain regions of the film due to the position of the hole made in the thin film. The calculation clearly shows that the hole can stabilize the spin vortex and sharpen the M - H loop transition, and may have potential applications in nanomagnets.
