Vortex Created by Skyrmion Spin Texture under Magnetic Field

Abstract

We show that a vortex current is created around a skyrmion spin texture under magnetic field due to a radial spin motive force in a two-dimensional metal with localized magnetic moments even in the absence of any superconductivity correlations. The effect is expected both for ferromagnetic and for antiferromagnetic systems. The Skyrmion-induced vortex mechanism provides a picture for large Nernst signals observed in the pseudogap phase of the high-$T_c$ cuprates.
