O. R. Baran, R. R. Levitskii

摘要:

在双粒子集团近似下研究了超立方晶格上的Blume-Emery-Griffiths模型。导出了$\bf{k}$空间中的成对关联函数的表达式。在所获得的结果的基础上(在$\bf{k}=0$)的静态磁化率的简单立方晶格上的这个模型计算在各种值的单离子各向异性和双二次相互作用。

英文摘要:

The Blume-Emery-Griffiths model on hypercubic lattices within the two-particle cluster approximation is investigated. The expressions for the pair correlation functions in $\bf{k}$-space are derived. On the basis of obtained results (at $\bf{k}=0$) the static susceptibility of this model on the simple cubic lattice is calculated at various values of the single-ion anisotropy and biquadratic interaction.
