- Abstract
We used a Monte Carlo simulation of the structurally disordered three dimensional Ising model. For the systems with spin concentrations p = 0:95; 0:8; 0:6 and 0:5 we calculated the correlation-length critical exponent by finite-size scaling. Extrapolations to the thermodynamic limit yield (0:95) = 0:705(5); (0:8) = 0:711(6); (0:6) = 0:736(6) and (0:5) = 0:744(6). The analysis of the results demon- strates the nonuniversality of the critical behavior in the disordered Ising model
