✦ Synopsis

Specific heat measurements

have been performed on a single-crystalline sample of the heavy-fermion compound UPt, in magnetic fields up to 24.5 T. The specific heat has been measured in the temperature range 1.8-40 K with an adiabatic method. The c/T values extrapolated to zero temperature for fields applied perpendicular to the hexagonal axis show a pronounced maximum near 20 T. This maximum was previously observed in measurements of differential susceptibility and magnetoresistivity.

The field effect in the specific heat is compared with the thermodynamically related temperature dependence of the susceptibility.
