| Abstract: | 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. |
