Infinite magnetoresistance in superconducting spin-valves with a nanometre-thick s-wave superconductor
*Jason Robinson1

This talk will review my group’s recent progress in generating pure spin supercurrents (1, 2) in superconducting proximity structures and the optimization of magnetic proximity effects in nm-thick s-wave superconductors. In particular, in the first part I will demonstrate spin-triplet pair generation via spin-orbit coupling and magnetic exchange fields1 and in the second part I will demonstrate infinite magnetoresistance in nm-thick layers of an s-wave superconductor on an insulating ferromagnet (3). The results are key to the development of superconducting spintronics (3, 4).
