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 $\nu$ by finite-size scaling. Extrapolations to the thermodynamic limit yield $\nu(0.95) = 0.705(5),\, \nu(0.8) = 0.711(6),\, \nu(0.6) = 0.736(6)$ and $\nu(0.5) = 0.744(6)$. The analysis of the results demonstrates the nonuniversality of the critical behavior in the disordered Ising model.
Keywords: complex temperature, critical exponents, disordered systems,zeroes of the partition function.
Mots-clés : Monte Carlo simulation
