Özet

The Blume-Capel model in the presence of external magnetic field H has been simulated using a cellular automaton algorithm improved from the Creutz cellular automaton in three-dimension lattice. The field critical exponent delta is estimated using the power law relations and the finite size scaling functions for the magnetization and the susceptibility in the range -0.1 <= h = H/J <= 0. The estimated value of the field critical exponent delta is in good agreement with the universal value (delta = 5) in three dimensions. The simulations are carried out on a simple cubic lattice under periodic boundary conditions.
