Generation of a superconducting vortex via N\'eel skyrmions

Abstract

We consider a type-II superconducting thin film in contact with a N\'eel skyrmion. The skyrmion induces spontaneous currents in the superconducting layer, which under the right condition generate a superconducting vortex in the absence of an external magnetic field. We compute the magnetic field and current distributions in the superconducting layer in the presence of N\'eel skyrmion.
