摘要：

The phase diagram of the unconventional superconductor UPt3 is explained under the long-standing hypothesis that the pair wave function belongs to the E1g representation of the point group. The main objection to this theory has been that it disagrees with the experimental phase diagram when a field is applied along the c axis. By a careful analysis of the free energy, this objection is shown to be incorrect. This singlet theory can also explain the unusual anisotropy in the upper critical field curves, often thought to indicate a triplet pair function, given that the in-plane susceptibility is Van Vleck-like and the out-of-plane susceptibility is Pauli-like. © 1995 The American Physical Society.
