Abstract
A model for a square-lattice ferrimagnet is investigated using ground-state analysis, Monte Carlo simulations, and numerical transfer-matrix studies. The model has spin 1/2 on one sublattice and spin 1 on the other sublattice, and all possible nearest-neighbor and field interactions. Our preliminary results indicate an Ising-like transition with no compensation point and no tricritical point, in disagreement with a mean-field analysis.
