摘要：

The specific heat of UTGe and ThTGe (T: Ni, Pd, Pt) has been measured by the semi-adiabatic heat-pulse method below 70 K. In three UTGe compounds, an anomaly of the specific heat was observed at each magnetic phase transition temperature. The values of the electronic specific heat coefficient were between 20 and 25 mJ/mol K2 for UTGe. The magnetic contribution to the specific heat is derived by subtracting the specific heat of ThTGe from that of the corresponding UTGe. The magnetic entropy of UTGe was estimated to be about R ln 2 near 50 K.
