Generation of pure superconducting spin current in magnetic heterostructures via nonlocally induced magnetism due to Landau Fermi liquid effects
The authors propose a novel mechanism for the creation of superconducting spin currents in a ferromagnet/superconductor/normal-metal heterostructure via a non-locally induced exchange field in the normal layer, which exhibits Landau Fermi liquid interactions. When the structure enters the superconducting state, spin-triplet superconducting correlations transfer spin across the superconductor and induce …
