Abstract

We investigate how domain structures of the ferromagnet in superconductor-ferromagnet heterostructures may change their transport properties. We calculate the distribution of current in the superconductor induced by magnetic field of Bloch domain walls, e.g., find the “lower critical” magnetization of the ferromagnet that provides vortices in the superconductor.
