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系统下的二维复式长方晶格的自旋波解.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饱和磁化强度MT/M0,并分析了系统基态的饱和磁化强度MT(A,B)/M0(A,B)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 model ferrimagnetism Heisenberg system through using Heisenberg exchange model and Green function. Through calculating associated function's operator and thermodynamic equilibration we obtained ground state magnetic induction M_(T(A,B))/M_(0(A,B)), and analyzed above physics quantities change rule along with spin quantum number and anisotropic parameter X_1,X_2,X_3.
