Our MC method has been extended to check the type of ordering and to determine the character of phase transitions and the positions of the boundaries of the mixed phase region in the three‐dimensional Ashkin‐Teller spin‐lattice model. Some results for this model on a cubic lattice are presented, which confirm the existence of such a region and determine the positions of its boundaries as well as the character of phase transitions.
