متن کاملHorizontal line nodes in superconducting Sr
We analyze the possibilities of triplet pairing in Sr 2 RuO 4 based upon an idea of interlayer coupling. We have considered two models differing by the effective interactions. In one model the quasi-particle spectra have horizontal line nodes on all three Fermi surface sheets, while in the other the spectra have line or point nodes on the α and β sheets and no nodes on the γ sheet. Both models ...
متن کاملInterband proximity effect and nodes of superconducting gap in Sr2RuO4.
The power-law temperature dependences of the specific heat, the nuclear relaxation rate, and the thermal conductivity suggest the presence of line nodes in the superconducting gap of Sr2RuO4. These recent experimental observations contradict the scenario of a nodeless (k(x)+ik(y))-type superconducting order parameter. We propose that interaction of superconducting order parameters on different ...
متن کاملOptical conductivity of superconducting Sr2RuO4
– We compute the optical conductivity of 2D f-wave superconductors and also of the multigap model proposed recently by Zhitomirsky and Rice at T = 0K in the Born limit. The presence of interband impurity scattering was found to play an important role: the contributions from the two bands mix up, and new structures are seen in the tunneling density of states and in the optical spectrum as well, ...
متن کاملSuperconducting transition of Ru in SQUIDs with Nb/Ru/Sr2RuO4 junctions
We have measured transport properties and magnetic responses of direct current superconducting quantum interference devices(dc-SQUIDs) with Nb/Ru/Sr2RuO4 junctions on the same Ru inclusion of a Sr2RuO4-Ru eutectic crystal. We observed a superconducting transition of the Ru at 0.50 K and another transition with anomalous interference patterns of the SQUID at 0.40 K. The second transition led to ...
