Abstract: Magnetic properties of a two-sublattice ferrimagnetwith antiferromagnetic exchange interaction inside one of the sublattices are calculatedwithin the framework of the molecular field theory taking into account the anisotropy of unstable sublattice. The magnetization curves of single crystal GdMn2Ge2 for the magnetic field parallel and perpendicularto thec-axis at different temperatures are calculated. Field-induced magnetic phase transitions in GdMn2Ge2 are discussed. CalculatedH-Tmagnetic phase diagrams are in fair agreement with experimental data.
