摘要：

We will review the superconducting properties of the layered compound Sr2RuO4, which exhibits unconventional superconductivity below 1.5 K. There are now several key experimental facts which strongly indicate that its superconducting symmetry is spin-triplet, p-wave. The results of the specific heat as well as the nulear relaxation rate, however, clearly deviate from the expectations for the simple p-wave state with an isotropic gap. We argue that the inclusion of the strong anisotropy and the observed multi-band features in the gap structure is needed to account for this deviation. Wherever appropriate, we will also make comparison with the properties of UPt3, the other superconductor widely recognized as triplet (C) 2000 Elsevier Science B.V. All rights reserved.
