Description

We examine a triplet Josephson junction where time-reversal symmetry is broken by the misalignment of the d-vectors of the triplet superconductors on either side of the junction. We demonstrate that a spontaneous magnetization of the tunneling barrier can be stabilized, with moment aligned along the direction mutually perpendicular to the two d-vectors. We then find that the free energy minimum lies at a phase difference intermediate between O and π, permitting the existence of fractional flux quanta at the junction barrier.
