Long-range ballistic transport mechanisms in superconducting spintronics

Résumé

We review the mechanisms responsible for long-range Josephson transport in ballistic hybrid superconductor/ferromagnet/superconductor (SFS) structures with the exchange field modulated in eigher coordinate or momentum space. these mechanisms are based on the suppression of the destructive interference of electron and hole waves in a ferromagnet caused by the exchange field. The interference suppression results in a slow decay of the singlet component of the pair correlation function in a ferromagnet and an increase in the Josephson current in SFS structures.
