Abstract
The critical behavior of the semi-infinite Ising model is investigated by means of the Monte Carlo method at different values of the exchange interaction between surface spins. The surface and bulk transitions are demonstrated to possess different temperatures if the surface energy is smaller than that of the bulk. A change in the behavior of surface thermodynamic functions is observed if the surface energy is much smaller than that of the bulk. The static critical indices of all phase transitions are calculated.
