Possible f -wave superconductivity in Sr 2 RuO 4 ?

Possible f - wave superconductivity in Sr 2 RuO 4 ?

– Until recently it has been believed that the superconductivity in Sr2RuO4 is described by p-wave pairing. However, both the recent specific heat and the magnetic penetration depth measurements on the purest single crystals of Sr2RuO4 appear to be explained more consistently in terms of f-wave superconductivity. In order to further this hypothesis, we study theoretically the thermodynamics and...

Unconventional superconductivity in Sr 2 RuO 4

We have performed ZF-lSR measurements of Sr 2 RuO 4 and have observed a spontaneous magnetic "eld below 1 # . This observation, combined with other symmetry considerations demonstrates that superconductivity in Sr 2 RuO 4 is of &p-wave' (odd-parity) type. Our transverse "eld lSR measurements in the mixed state with B"150 GDDc( clearly indicate the presence of a square #ux lattice. We have analy...

0 Superconductivity In Disordered Sr 2 RuO

Recent experimental evidence suggests that the Cooper pairs in superconducting Sr2RuO4 are triplets with p-wave internal symmetry, as in the case of superfluid 3He1–4. One of characteristic features of this exotic state is the strong influence of impurities on its superconducting properties. Studies of the electronic structure in Sr2RuO4 2 have identified an extended van Hove singularity close ...

P-wave Pairing in Superconducting Sr 2 Ruo 4

Is Sr(2)RuO(4) a chiral p-wave superconductor?

Much excitement surrounds the possibility that strontium ruthenate exhibits chiral p-wave superconducting order. Such order would be a solid state analogue of the A phase of He-3, with the potential for leading to exotic physics relevant to quantum computing. We take a critical look at the evidence for such time reversal symmetry breaking order. The possible superconducting order parameter symm...
