Abstract

We present a theoretical analysis of a triplet superconductor–ferromagnet–triplet superconductor (TFT) junction. We describe in detail the construction of the quasiclassical scattering Green's function and provide a derivation of the general expression for the Josephson current between two triplet superconductors. Specializing to the TFT junction, we compare and contrast the dependence of the Andreev bound state energies and the current upon the scattering at the ferromagnetic barrier, for the two cases of aligned and mis-aligned d-vectors in the triplet superconductors. We also discuss the unconventional temperature-dependence of the current through the junction.
