Competition between the superconducting spin-valve effect and quasiparticle spin-decay in superconducting spin-valves

Abstract

Superconducting spintronics aims to utilise the interaction between magnetic order and superconductivity in order to enhance the performance of a spintronics-based device. Here, the authors experimentally investigate a superconducting spin valve and report a crossover from giant magnetoresistance to the superconducting spin-valve effect as function of material thickness.
