Anisotropic Superconductivity in MoGe - Permalloy Bilayers
ORAL
Abstract
We studied the magneto-transport properties of superconductor-ferromagnet MoGe/Permalloy bilayers. The ferromagnet with stripe domain structure induces in-plane anisotropy in superconducting order parameter. Superconducting phase diagram shows that near the S-N phase boundary the superconductivity is localized in narrow mesoscopic channels just above the magnetic domain walls. By changing the in-plane direction of magnetic stripe domains it is possible to re-configure the direction of the superconducting channels and enable one to control the direction of the anisotropy axis in the superconductor.
