摘要：

The critical behavior and the magnetic properties of the spin 3/2 Blume-Emery-Griffiths model have been investigated on a square lattice within the framework of an effective field theory based on the use of a probability distribution technique. The effect of the transverse crystal field D-x on the magnetic properties is examined. The model presents very rich critical behavior, which includes first and second order phase transitions. The tricritical, isolated critical, and critical end points are also observed.
