Abstract: The ferromagnetic properties of the spin-1 BEG model on finite-size Cayleytree are investigated using the exact recursion method. The spontaneousmagnetization of the system is studied in detail for different values of thereduced crystal-field interaction D-J, and it is found that there is an unusualbehavior anti-Curie temperature when D-J>2.0. We also obtain the Curietemperature of this finite-size system. When the system size is large enough,our results will fit well with that in the thermodynamic limit.
