We report experimental results and careful analysis on high precision measure-ments of magnetic specific heat capacities C, of three-dimentional (3D) anti-ferromagnets, CoF., MnF. and KMnF3 by means of AC calorimetric method.CoF. behaves like a 3D Ising antiferromagnet in the entire critical region nearthe N<set temperature 7'N. On the other hand, a careful analysis of the experimentaldata in the temperature region vcry close to IN of both MOF2 and KMnF, showsan interesting phenomenon. On approaching to T., a crossover from 3D Heisen-berg behavior to 3D Ising one is observed.
