By using the mean-field approximation method, the critical behavior of the mixed-spin XXZ model with DM interaction on the cubic lattice is studied.
利用平均场近似的方法，研究了立方晶格上具有DM相互作用的混合XXZ模型的相变和临界性质。

In this treatment, the effects of solvent and meanfield of surrounding ions have been considered by virtue of an effective interionic pair potential and the three-body interaction is neglected.
