Voltage control of superconducting exchange interaction and anomalous Josephson effect

摘要: Exerting control over the magnetic exchange interaction in heterostructures is of both basic interest and has potential for use spin-based applications relying on quantum effects. We show that sign a spin valve, determining whether parallel (p) or antiparallel (ap) configuration favored, can be controlled via an electric voltage. This occurs due to interplay between nonequilibrium quasiparticle distribution presence spin-polarized Cooper pairs. Additionally, we voltage-induced controls anomalous supercurrent Josephson junctions, obviating challenging task manipulate texture system. demonstrates two key phenomena superconducting spintronics, phase shift generating effect, electrically. Our findings are relevance devices which practice likely have operated precisely by
