【 摘 要 】

We examine the superconducting gap nodes in crystals with tetrahedral (T-h) symmetry. The (0, 0, 1) phase of the three-dimensional order parameter in the triplet channel has nodes in the [001] directions. Following a second order phase transition to the state (0; i vertical bar eta(2)vertical bar, vertical bar eta 1 vertical bar), each node lifts away from the Fermi surface and splits into two deep dips. We discuss this scenario in the context of multiple superconducting phases in PrOs4Sb12. (c) 2006 Elsevier B. V. All rights reserved.
