Josephson Effect in Singlet Superconductor-Ferromagnet-Triplet Superconductor Junction

Superconductivity 2018-03-14 v1

Abstract

We study the current-phase relation of a ballistic SIFIT junction, consisting of a spin-singlet superconductor (S), a weak ferromagnetic metal (F), a spin-triplet superconductor (T), and insulating ferromagnetic interfaces (I). We use the generalized quasiclassical formalism developed by A. Millis et al. to compute the current density and the free energy of the junction for arbitrary orientation of the magnetizations of the junction barrier. We investigate in detail the effect of the distribution of magnetization on the various harmonics of the current-phase relation and the transition of the ground state of the junction. The ϕ\phi-state junction can be realized for a noncollinear orientation of the barrier magnetizations in the plane perpendicular to the d-vector of the triplet superconductor.
