Abstract

The specific heat of UO₂ single crystals is measured in the temperature range of 0.3 to 50 K. This investigation indicates a very sharp first order transition at 30.3 K rather than the λ‐type anomaly reported to occur at 28.7 K as a consequence of magnetic ordering. The specific heat at the peak of the transition is about six times as high as that previously reported. The specific heat results are compared with those derived from neutron scattering and with other existing theories.
