Josephson effect test for triplet pairing symmetry

The critical current modulation and the spontaneous flux of the vortex states in corner Josephson junctions between Sr2RuO4 and a conventional s-wave superconductor are calculated as a function of the crystal orientation, and the magnetic field. For Sr2RuO4 we assume two nodeless p-wave pairing states. Also we use the nodal f -wave states B1g × Eu and B2g × Eu, and one special p-wave state havi...

Long-range superharmonic Josephson current and spin-triplet pairing correlations in a junction with ferromagnetic bilayers

The long-range spin-triplet supercurrent transport is an interesting phenomenon in the superconductor/ferromagnet () heterostructure containing noncollinear magnetic domains. Here we study the long-range superharmonic Josephson current in asymmetric junctions. It is demonstrated that this current is induced by spin-triplet pairs  -  or  +  in the thick layer. The magnetic rotation of the partic...

Superfluid Phases of Triplet Pairing

Two-Gap Superconductivity in LaNiGa_{2} with Nonunitary Triplet Pairing and Even Parity Gap Symmetry.

The nature of the pairing states of superconducting LaNiC_{2} and LaNiGa_{2} has to date remained a puzzling question. Broken time reversal symmetry has been observed in both compounds and a group theoretical analysis implies a nonunitary triplet pairing state. However, all the allowed nonunitary triplet states have nodal gap functions but most thermodynamic and NMR measurements indicate fully ...

What Does Instrinsic Josephson Coupling Say about the Pairing Symmetry in the Cuprates?

Measurements of the c-axis properties of the cuprate superconductors show anomalous behavior in both normal and superconducting states. In particulaL there is strong evidence that pairs of CuO2 planes in neighboring unit cells act as Josephson junctions below the critical temperature Tr We present a theory based on incoherent transport Mong the c-axis which naturally reproduces the anisotropic ...
