Triplet Josephson effect with magnetic feedback in a superconductor-ferromagnet heterostructure.
We study the ac Josephson effect in a superconductor-ferromagnet heterostructure with a variable magnetic configuration. The system supports triplet proximity correlations whose dynamics is coupled to the magnetic dynamics. This feedback dramatically modifies the behavior of the junction. The current-phase relation becomes double periodic at both very low and high Josephson frequencies omegaJ. At intermediate frequencies, the periodicity in omegaJt may be lost.
