Abstract

We studied new structures of superconducting spin valves of Fe2/Nb/Fe1/CoO_x and Fe2/Al₂O₃/Nb/Al₂O₃/Fe1/CoO_x designs. The operation of these structures is built beyond the classical superconductor/ferromagnet proximity effect. The superconductor/ferromagnet interface in these structures is separated by an additional insulating layer. According to the results of our studies, the Fe2/Al₂O₃/Nb/Al₂O₃/Fe1/CoO_x structures are the most promising structures for further research.
