The simulation of the two-dimensional Ising model in the presence of an external magnetic field on the Creutz cellular automaton

The two-dimensional Ising model in a small external magnetic field, is simu lated on the Creutz cellular automaton. The values of the static critical e xponents for 0.0025 less than or equal to h less than or equal to 0.025 are estimated within the framework of the finite size scaling theory. The valu e of the field critical exponent is in a good agreement with its theoretica l value of delta = 15. The results for 0.0025 less than or equal to h less than or equal to 0.025 are compatible with Ising critical behavior for T < T-c.
