Abstract
Two-sublattice collinear Heisenberg-Ising (S = 1) metamagnets with uniaxial three-ion anisotropy are investigated. Thermodynamical properties of this model are examined in the approximation including Gaussian fluctuations of the molecular field. The complete phase diagrams are obtained numerically. The theoretical results fitted for the FeCl2 metamagnet are compared with experimental ones.
