We study the temperature and field dependence of the magnetization M(T,H) for the order-disorder transition in DMMn and the chromium-doped DMMn close to T-c. By analyzing the experimental data for M(T,H) from the literature according to the power-law formula, values of the critical exponent (beta) and the critical isotherm (delta) are deduced and also, the temperature dependence of magnetization M(T) is calculated from the molecular field theory for those compounds.
