Abstract

Magnetic properties of a two-sublattice ferrimagnet with antiferromagnetic exchange interaction inside one of the sublattices are calculated within 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 perpendicular to the c-axis at different temperatures are calculated. Field-induced magnetic phase transitions in GdMn2Ge2 are discussed. Calculated H - T magnetic phase diagrams are in fair agreement with experimental data.
