"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," researchers in the United States report.
"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," wrote G. Karapetrov and colleagues.
