title: Periodic magnetoresistance oscillations induced by superconducting vortices in single crystal Au nanowires.
abstract: We show in this paper that it is possible to induce superconducting vortices in a gold nanowire connected to superconducting electrodes. The gold nanowire acquires superconductivity by the proximity effect. The differential magnetoresistance of the nanowire beyond a critical magnetic field shows uniform oscillations with increasing field with a period of Φ(0)/(2πr(2)) (Φ(0) = h/2e is the superconducting flux quantum, r = 35 nm is the radius of the nanowire). Our analysis indicates that these periodic oscillations are the signatures of the sequential generation and moving of vortices across the gold nanowire.
