Coexistence and tuning of spin-singlet and triplet transport in spin-filter Josephson junctions

Abstract

Heterostructures comprising of different materials provide the possibility to engineer devices with specific properties based on the individual characteristics and interactions between the different components. Here, the authors report the detection of proximity-induced spin-triplet Cooper pairs in a superconductor/ferromagnet/superconductor Josephson junction made of NbN and GdN respectively.
