摘要: The ferromagnetic properties of the spin-1 BEG model on finite-size Cayley tree are investigated using exact recursion method. spontaneous magnetization system is studied in detail for different values reduced crystal-field interaction D/J, and it found that there an unusual behavior (anti-Curie temperature) when D/J > 2.0. We also obtain Curie temperature this system. When size large enough, our results will fit well with thermodynamic limit.
