Abstract

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 ³He. Here we present an analysis of the thermodynamic properties in these two superconducting states within the weak-coupling BCS theory.
