Spin and Charge Currents in SNS Josephson Junction with f-wave Pairing Symmetry

Abstract

We study transport properties and also local density of states in a clean superconductor-normal metal-superconductor Josephson junction with triplet f-wave superconductors based on the Eilenberger equation. Effects of thickness of normal metal and misorientation between gap vector of superconductors on the spin and charge currents are investigated. Spin current, which stems from the misalignment of d-vectors, in the absence of charge current for some values of phase difference between superconductors is found. We also find unconventional behavior of the spin current associated with 0-pitransition. The misalignment of d-vectors also gives rise to a zero energy peak in the density of states in the normal metal.
