- 論文の詳細を見る
Phase transitions of a spin-one Ising model with positive biquadratic infer-action are investigated using a Monte Cargo method for a square lattice in com-parison with the molecular-field results obtained from a two-sublattice model.Phase diagrams characterizing phase transitions of the model are presented forrepresentative values of energy parameters and compared with those obtainedfrom the molecular-field theory and other theories. It is shown that there existno successive phase transitions as predicted from the molecular-field theory forany value of energy parameters we dealt with. Multicritical points on phaseboundaries are estimated from the data to give reasonable values compared withthose of other theories.
