利用Heisenberg交换作用模型、格林函数法研究了X Y Z模型亚铁磁性Heisenberg系统下的二维长方复式晶格(P211)的自旋波解.通过求解算符的关联函数和热力学系统平均值得到了系统基态的内能U,并分析了系统基态的内能U随自旋量子数、各向异性参数X1、X2、X3的变化规律.

In this paper, we have studied the two-dimensional rectangle double lattice (p211) spin wave solution under X-Y-Z mode ferrimagnetism Heisenberg system with Heisenberg exchange mode and Green function. By Solving associated function's operator and thermodynamic equilibration, we have obtained ground state inner energy U, and analyzed above physic quantities changing with spin quantum number and the Changing rule of anisotropic parameter X_1,X_2,X_3.
