Tunable transport in magnetically coupled MoGe/permalloy hybrids.
We demonstrate controlled magnetotransport anisotropy of magnetically coupled superconductor-ferromagnet MoGe/Permalloy hybrids. The rotatable anisotropy Permalloy ferromagnet with stripe domain structure induces in-plane anisotropy in superconducting order parameter. We show that near the superconductor-normal state phase boundary the superconductivity in MoGe is localized in narrow mesoscopic channels just above the magnetic domain walls. Changing the in-plane direction of magnetic stripe domains it is possible to reconfigure the direction of the superconducting channels and controllably rotate the direction of the in-plane anisotropy axis in the superconductor.
