摘要：
In PrOS4Sb12, the lowest-lying singlet and triplet states in a Pr 4f(2) configuration hybridize with conduction electrons having local a(u) and t(u) point-group symmetries. It is shown that for an attractive triplet pairing interaction, the orbital degrees of freedom of the t(u) component are important. In addition, the T-h, point-group symmetry characteristic of skutterudites plays an important role in stabilizing triplet superconductivity.
