Spin-polarized quasiparticle transport in exchange-split superconducting aluminum on europium sulfide

Wolf, M.J.; Sürgers, Christoph; Fischer, Gerda; Beckmann, D.

Abstract: We report on nonlocal spin transport in mesoscopic superconducting aluminum wires in contact with the ferromagnetic insulator europium sulfide. We find spin injection and long-range spin transport in the regime of the exchange splitting induced by europium sulfide. Our results demonstrate that spin transport in superconductors can be manipulated by ferromagnetic insulators, and opens a path to control spin currents in superconductors.
