A theory of new type of heavy-electron superconductivity in PrOs4Sb12: quadrupolar-fluctuation mediated odd-parity pairings
It is shown that unconventional nature of superconducting state of PrOs4Sb12, a Pr-based heavy electron compound with the filled-Skutterudite structure, can be explained in a unified way by taking into account the structure of the crystallineelectric-field (CEF) level, the shape of the Fermi surface determined by the band structure calculation, and a picture of the quasiparticles in f-configura...
متن کاملAnisotropic superconductivity in PrOs4Sb12
Recently two anisotropic superconducting gap functions have been observed in the skutterudite PrOs4Sb12. These order parameters are spin-triplet. There are at least 2 distinct phases in a magnetic field, bearing some resemblance to superfluid He. Here we present an analysis of the thermodynamic properties in these two superconducting states within the weak-coupling BCS theory. PACS. 74.20.Fg BC...
متن کاملDirect observation of quadrupolar excitons in the heavy-fermion superconductor PrOs4Sb12.
We report inelastic neutron scattering experiments performed to investigate the low energy magnetic excitations on single crystals of the heavy-fermion superconductor PrOs(4)Sb(12). The observed excitation clearly softens at a wave vector Q=(1,0,0), which is the same as the modulation vector of the field-induced antiferro-quadrupolar ordering, and its intensity at Q=(1,0,0) is smaller than that...

Supporting Online Material “Odd-Parity Superconductivity in Sr2RuO4”
1. Materials and sample preparation High-quality single crystals of Sr2RuO4 used in this work were grown by the floatingzone technique and characterized in detail by standard techniques (S1). We found in the course of this work that crystals with an optimal superconducting transition temperature (Tc) around 1.5 K typically have more Ru inclusions than those with slightly lower Tc. However, thos...
