| Abstract: | 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. |
