| Abstract: | The critical behavior of the specific heat of small magnetic particles of the real antiferromagnet Cr2O3 is investigated by the Monte-Carlo method. The critical indices α=−0.17±0.03 and the ratio of the critical amplitudes A/A′=1.03±0.07 are calculated for particles containing N=286 to 2502 spins.
