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

Superconductivity 2014-10-17 v1 Mesoscale and Nanoscale Physics

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 new path to control spin currents in superconductors.
