Controlled suppression of superconductivity by the generation of polarized Cooper pairs in spin-valve structures

Abstract

The authors create an unconventional superconducting state in the vicinity of noncollinear ferromagnetic interfaces. In particular, they use Co spin-valve structures to modify the superconducting state of Nb, a conventional superconductor, by the controlled generation of equal spin superconducting triplets from the singlet ground state.
