Query: Critical behavior of a 2D spin-pseudospin model in a strong exchange
  limit   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.
