Acesso em: 11 set. 2023.2470-0045https://arxiv.org/abs/1808.06702A classic three-dimensional spin model, based upon the Baxter-Wu scheme, is presented. It is found, by entropic sampling simulations, that the behavior of the energy and magnetization fourthorder cumulants points out to a first order phase transition. A finite-size procedure was performed, confirming that the system scales with the dimensionality d = 3, and yielding a high-resolution estimate of the critical temperature as Tc = 11.377577(39).engAcesso RestritoArtigo10.1103/PhysRevE.100.032141e- 2470-0053
