摘要：

The critical properties of two-dimensional antiferromagnetic Ising model in square lattice are investigated using the replica Monte-Carlo method with account of interactions of second nearest neighbors. The diagram of critical temperature dependence on an interaction value of second nearest neighbors is plotted. Static critical exponents of the heat capacity alpha, susceptibility gamma, magnetization beta, and correlation radius. are calculated for this model using the finite-size scaling theory.
