Abstract: The phase diagram of an antiferromagnet with the spin crossover from the high-spin to low-spin state with $S$ = 0 with increasing external pressure has been calculated with regard to the pressure dependence of the exchange integral. The calculated results are compared with the experimental data on ferropericlase Fe$_{x}$Mg$_{1-x}$O.
