Abstract
The two-dimensional model (antiferromagnetic and ferromagnetic bonds at random) is studied by transfer-matrix and Monte Carlo calculations. Large clusters of spins pointing in one direction are found for ( being the concentration of negative bonds). Evidence against a phase transition at finite temperature is found by investigating the correlation function ..
