The effect of random bond dilution on the phase transition of the three-dimensional four-state Potts model was studied using Monte Carlo simulation. The phase diagram in the dilution-temperature plane was also determined from the peaks of the susceptibility for sufficiently large system sizes. It was observed that critical exponent ν governing the scaling behavior of the correlation length is compatible with that of the 3D site Ising model. |
