✦ Synopsis

Temperature dependence of the specific heat was measured on a single crystal of UNiGa in magnetic fields. The value 3' = 40.9 mJ/mol K 2 does not change with the field-induced transition. The magnetic entropy is larger in the high-field (ferromagnetic) state (0.55 x R In2) than in the AF ground state (0.50 x R ln2). Thermodynamic analysis shows that the high-field state is a true ferromagnetic state.
