Quantum limit of the triplet proximity effect in half-metal - superconductor junctions
B. Béri, J. N. Kupferschmidt, C. W. J. Beenakker +1
We apply the scattering matrix approach to the triplet proximity effect in superconductor-half metal structures. We find that for junctions that do not mix different orbital modes,…
Spin torque in a magnetic trilayer coupled to a superconductor
Xavier Waintal, Piet W. Brouwer
A ferromagnet-normal-metal-ferromagnet trilayer does not conserve spin current and as a result, the conduction electrons can create a torque on the magnetic moments. When the trila…
Competition between zero bias anomaly and proximity effect in disordered systems
Yuval Oreg, P. W. Brouwer, B. D. Simons +1
We investigate the suppression of the proximity effect in mesoscopic normal metal/superconductor systems induced by Coulomb interaction. We identify and elucidate the mechanism by…
