Spin polarized transport in the weak-link between $f$-wave superconductors

Abstract

The spin current in the Josephson junction as a weak link (interface) between misorientated triplet superconductors is investigated theoretically for the models of the order parameter in $UP{t}_3$. Green functions of the system are obtained from the quasiclassical Eilenberger equations. The analytical results for the charge and spin currents are illustrated by numerical calculations for the certain misorientation angles of gap vector of superconductors. As the main result of this paper, it is found that, at some values of the phase difference, at which the charge current is exactly zero, the spin current has its maximum value. Furthermore, it is shown that the origin of spin current is the misorientation between gap vectors of triplet superconductors.
