Abstract
The heat capacity of a Cr2O3 antiferromagnet near the critical temperature is precisely measured by ac calorimetry. The critical behavior of the heat capacity is examined. The regularities of variations in the universal criti cal parameters near the critical point are determined, and their values are calculated. A crossover from the Heisenberg (n = 3) to the Ising (n = 1) c ritical behavior is revealed. (C) 2001 MAIK "Nauka/Interperiodica".
