摘要：

To clarify the origin of anomalous behaviors in Pb/Sr2RuO4/Pb junctions in terms of the pairing symmetry, a theory of the d.c. Josephson current in s-wave superconductor/p-wave superconductor/s-wave superconductor junctions is developed. Calculated results on the temperature dependence of the critical Josephson current show nonmonotonic behavior when the thickness of the p-wave superconductor is comparable to the coherence length. The consistency between the present results with recent experimental measurements support the possibility of a unitary p-wave pairing state in Sr2RuO4.
