摘要：

In this paper we present a thermodynamic analysis of the UPt3 superconducting phase diagram in the H-T plane. The analysis relates the specific-heat jumps to the slopes of the four phase-transition lines. The existing data are found to be in good mutual agreement, and consistent with the assumption that the inner phase-transition line at low field, T(c)*, is second order for both H perpendicular-to c and H parallel-to c. For H perpendicular-to c, the inner phase-transition line at higher field, H(FL), is first order albeit with a small latent heat. For H parallel-to c, it can be second order.
