摘要：

We study the antiferromagnetic O(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 --> infinity limit is also considered with analytical methods. (C) 1998 Elsevier Science B.V.
