Domain wall effects in ferromagnet-superconductor structures

arXiv:cond-mat/0501210 · doi:10.1103/PhysRevB.72.144520

Abstract

We investigate how domain structure 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, find the ``lower critical'' magnetization of the ferromagnet that provides vortices in the superconductor.
