Spontaneous currents in superconducting systems with strong spin-orbit coupling

Superconductivity 2017-04-14 v1

Abstract

We show that Rashba spin-orbit coupling at the interface between a superconductor and a ferromagnet should produce a spontaneous current in the atomic thickness region near the interface. This current is counter-balanced by the superconducting screening current flowing in the region of the width of the London penetration depth near the interface. Such current carrying state creates a magnetic field near the superconductor surface, generates a stray magnetic field outside the sample edges, changes the slope of the temperature dependence of the critical field Hc3H_{c3} and may generate the spontaneous Abrikosov vortices near the interface.
