| الوصف: | We study the 2D static spin-pseudospin model equivalent to the dilute frustrated antiferromagnetic Ising model with charge impurities. We present the results of classical Monte Carlo simulation on a square lattice with periodic boundary conditions in a strong exchange limit. In the framework of the finite-size scaling theory we obtained the static critical exponents for the specific heat $\alpha$ and the correlation length $\nu$ for a wide range of the local density-density interaction parameter $\Delta$ and charge density $n$. It was shown that the system exhibits non-universal critical behavior depending on these parameters. Comment: 7 pages, 2 figures |
