We have employed for the simulations dedicated Pentium Pro machines (RTNN project). J.M. Carmona is a Spanish MEC fellow.We study the antiferromagnetic O(N). N model in the F_(4) lattice. Monte Carlo simulations are applied for investigating the behavior of the transition for N = 2,3. The numerical results show a first order nature but with a large correlation length. The N = ∞ limit is also considered with analytical methods.engjournal articlehttp://doi.org/10.1016/S0370-2693(97)01292-6http://www.sciencedirect.com/open access5351-73Phase-transitions3 dimensionsMonte-Carlo.Física (Física)Física-Modelos matemáticos22 Física
