Abstract
We demonstrate novel magneto-transport properties of magnetically coupled superconductor-ferromagnet (MoGe/Permalloy) bilayers. Ferromagnetic Permalloy film exhibiting stripe domains with rotatable anisotropy induces modulation of the order parameter in the superconducting thin film. Domain-wall superconductivity is localized above the magnetic domain walls forming mesoscopic superfluid channels. We can achieve non-volatile re-configuration of the in-plane direction of the superconducting channels by changing the orientation of the stripe domains in the Permalloy. We discuss the influence of magnetic domain structure on Abrikosov vortex dynamics in this system.
