Resumo: The mean field theory results are obtained from the Bogoliubov inequality for the spin-1/2 Ashkin-Teller model on a cubic lattice for different cluster sizes. The phase diagram, magnetization and free energy are obtained. From those expressions we observed a new phase in the model. Denoted in the course of this work by Baxter((2)) this new phase presents < S > not equal <sigma > not equal 0. The phase transitions between the Baxter((2)) and the others well known phases for the model are studied and classified. (C) 2017 Elsevier B.V. All rights reserved.
