Magnetic Josephson junctions with noncentrosymmetric superconductors

We study the dc Josephson effect in a clean noncentrosymmetric superconductor/ferromagnet/noncentrosymmetric superconductor junction within the quasiclassical theory of superconductivity. By considering charge and spin currents, we show that in such junctions an exotic Josephson effect can take place, depending on the superconducting pairing state and spin polarization direction. We focus on the importance of spin-triplet/spin-singlet gaps ratio in such systems showing that its value is related to the existence of even and odd high-order harmonics in the charge and spin current-phase relations, and to the possibility of 0-pi transitions.
