Phase diagrams of Ising films with competing interactions
arXiv:cond-mat/0203395 · doi:10.1140/epjb/e2002-00161-6
Abstract
The axial next-nearest-neighbour Ising (ANNNI) model of finite thickness is studied. Using mean-field theory, Monte Carlo simulations, and low-temperature analyses, phase diagrams are determined, with a distinct phase diagram for each film thickness. The robustness of the phase diagrams against varying the couplings in the surface layers is analysed.
