摘要：

A tricritical point introducing dipolar and quadropolar exchange interaction in a spin-1 Ising model is defined exactly. The phase diagrams for different values of the dipolar and quadropolar exchange interactions are given and the second-order phase transition defined by the quadropolar moment is found. The tricritical exponents are calculated exactly. © 1990.
