چکیده
The filled skutterudite compound PrOs4Sb12 has been found to exhibit superconductivity with a critical temperature Tc = 1.85 K that develops out of a heavy Fermi liquid with an effective mass m ∗ ≈ 50 me. The current experimental situation regarding the heavy fermion state, the superconducting state, and a high field, low temperature phase that is apparently associated with magnetic or quadrupolar order in PrOs4Sb12 is briefly reviewed herein.

Time-reversal symmetry-breaking superconductivity in heavy-fermion PrOs4Sb12 detected by muon-spin relaxation.
We report on muon-spin relaxation measurements of the 4f(2)-based heavy-fermion superconductor filled-skutterudite Pr(Os4Sb12. The results reveal the spontaneous appearance of static internal magnetic fields below the superconducting transition temperature, providing unambiguous evidence for the breaking of time-reversal symmetry in the superconducting state. A discussion is made on which of th...

– Recently the superconducting gap functions of the skutterudite PrOs4Sb12 have been proposed [K. Maki et al, Europhys. Lett. 68, 720 (2004)]. The superconductivity is spin-triplet and consists of at least 2 distinct phases in a magnetic field, which bears some resemblance to superfluid 3 He. Here we present our analysis of the thermodynamic properties of these two superconducting states within...

The filled skutterudite compound PrOs4Sb12, the first example of a Pr-based heavy fermion superconductor, displays superconductivity with Tc ∼ 1.85 K and has an effective mass m ∗ ∼ 50 me, where me is the free electron mass. For magnetic fields above 4.5 T, sharp features in the normal state electrical resistivity, magnetization, specific heat, and thermal expansion data suggest the occurrence ...
