摘要：

Specific heat measurements on UNiAl in magnetic fields up to 20 T demonstrate that the Neel temperature (T(N) = 19 K) is drastically reduced by magnetic fields B parallel-to c-axis. AF ordering disappears for B > 11.35 T, the field of the metamagnetic transition. A step in gamma-versus B (to congruent-to 250 mJ/mol K2) observed just above the critical field separates the low-field increasing tendency from the high-field decrease. At 20 T, a gamma-value smaller than the zero-field value of 163 mJ/mol K2 is found.
