The pressure dependence of the ferromagnetic-paramagnetic phase transition temperature T_{C} (p) is of high interest due to its direct technological implications. The theoretical investigations of the Curie temperature T_{C} (p) considered in the ferromagnetic crystals have been studied employing various methods of calculations. The present paper is devoted to its description by means of the pseudoharmonic approximation approach.
