Critical-current oscillations in superconductor-ferromagnet-superconductor structure taking s-d scattering into account

The critical current in a Josephson junction with a weakly ferromagnetic layer of a transition-metal alloy is calculated. The Gor’kov equations are solved taking the s-d scattering in a ferromagnet into account. It is shown that consideration of this scattering, which results in the destruction of Cooper pairs, makes it possible to achieve good agreement with experiments which could not be explained by other models.
