Anomalous interaction between vortices and nanomagnets

Abstract
We study a thin film system consisting of a superconducting and a magnetic film, where the superconductor contains a vortex and the magnetic film a nanomagnet. We find that if the magnetic film has planar anisotropy, the vortex induces a magnetization distribution, and its interaction with the nanomagnet crosses over from attractive to repulsive at short distances.
