Studying Features of an Fe/Nb-Based Superconducting Spin Valve

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

A study is performed of new Fe2/Nb/Fe1/CoOx and Fe2/Al2O3/Nb/Al2O3/Fe1/CoOx superconducting spin valve structures that operate beyond the classical superconductor/ferromagnet proximity effect. The superconductor/ferromagnet interface in these structures is separated by an additional insulating layer. It is shown that the Fe2/Al2O3/Nb/Al2O3/Fe1/CoOx structures are most promising for further investigations.
