The effects of configurational, quenched, bond randomness on the critical properties of the nearest-neighbour Ising model are studied in two and three dimensions by a real space renorrealization group method.

The long ranged Gaussian random Ising bond model and short ranged binary random Ising bond model are discussed by the method of the pair approximation of the cluster variation and by the method of the integral equation for the distribution function of the effective fields. For the long ranged model,
An Ising Hamiltonian, which includes diluted and random bonds, and the Mean Field Renormalization Group (MFRG) technique were used to obtain a theoretical phase diagram as a function of the antiferromagnetic sites concentration for the Fe x Mn 0.6Γx Al 0.4 system. A probability distribution was prop
