Increasing the performance of the superconducting spin valve using a Heusler alloy

A. A. Kamashev, A. A. Validov, J. Schumann +4

We have studied superconducting properties of the spin-valve thin layer heterostructures CoO${}_x$/F1/Cu/F2/Cu/Pb where the ferromagnetic F1 layer was standardly made of Permalloy wh…
