Monte Carlo study of mixed spin-1 and spin-3/2 Ising ferromagnet

Summary form only given. Recently, the mixed spin-1 and spin-3/2 Ising system has been investigated with use of an effective field theory and a cluster variational method. However, there are some disagreements between those theoretical studies as to the existence of tricritical points and other features. Furthermore, a great variety of topologies of the finite temperature phase diagram is predicted by the cluster variational method for the cubic lattice. To help to resolve these differences we study the same model by Monte Carlo simulations.
