Transport of charge and spin in the weak link between misoriented PrOs 4Sb12 superconductors

Abstract

Recently, the '(p + h)-wave' form of pairing symmetry has been proposed for the superconductivity in the PrOs4Sb12 compound (Parker et al 2004 Preprint cond-mat/0407254). In the present paper, a stationary Josephson junction as a weak-link between PrOs4Sb 12 triplet superconductors is theoretically investigated. The quasiclassical Eilenberger equations are analytically solved. The spin and charge current-phase diagrams are plotted, and the effect of misorientation between crystals on the spin current and spontaneous and Josephson currents is studied. It is found that such experimental investigations of the current-phase diagrams can be used to test the pairing symmetry in the above-mentioned superconductors. It is shown that this apparatus can be applied as a polarizer for the spin current. © 2005 IOP Publishing Ltd.
