摘要
Monte-Carlo computer simulation is employed to investigate the surface phase transition (PT) in the 3D semibounded antiferromagnetic Ising model. Simulation is performed at different ratios of exchange integrals on the system surface and in its bulk. The dependence between the PT temperature and the distance to the surface is studied. When the ratio of exchange integrals is less than 1.38, the PT temperature is found to increase with distance from the surface. A comparison with the results of a real experiment is carried out. The simulation results are demonstrated to be in qualitative and quantitative agreement with experimental data. © 2018, Pleiades Publishing, Ltd.
