摘要：
A spin-3/2 random-field Ising model with a crystal field on the honeycomb lattice is studied within the framework of the effective-field theory with correlations. We have investigated the effect of the crystal field on the phase diagrams, magnetizations, quadrupolar moments of the system. The phase diagram exhibits a rich variety of behaviors: the reentrant phenomena and the existence of tricritical points. (C) 2003 Elsevier B.V. All rights reserved.
