Summary: | Anomalous features of the proximity effect specific to diffusive normal metal (DN) / triplet superconductor junctions are studied within the quasiclassical Green¿s function formalism. The pair amplitude fN as a function of energy ¿ in DN, satisfies an anomalous relation, fN(¿)=¿fN*(¿¿) , contrary to that in singlet superconductor junctions case where fN(¿)=fN*(¿¿) . Such an unusual ¿ dependence is responsible for a zero energy peak in the local density of states and is a source of an anomalous penetration of the applied magnetic field into DN. Our results are relevant to Sr2RuO4 , which is considered to have a px+ipy -wave symmetry. |
