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.

FeCl2超磁体理论

研究了具有单轴三离子各向异性的双亚晶格共线Heisenberg-Ising (S = 1)超磁体。在包含分子场高斯涨落的近似下考察了该模型的热力学性质。用数值方法得到了完整的相图。对FeCl2超磁体的理论拟合结果与实验结果进行了比较。
