中文摘要The phase diagram of mixed spin-3/2 and spin-2 Ising ferromagnetic model with different single-ion an isotropies is investigated by the use of a mean-field theory based on the Bogoliubov inequality for the Gibbs free energy. Global phase diagrams are obtained in the temperature-anisotropy plane. In particular, by changing values of the single-ion anisotropies, several different types of phase diagrams of first-order transition between two ordered phases, are studied in detail. A variety of multicritical points such as tricritical points, isolated critical points, and triple points are obtained. (C) 2009 Elsevier B.V. All rights reserved.
