Abstract
Ising models with nearest neighbor ferromagnetic random couplings on a square lattice with a (1, 1) surface are studied, using Monte Carlo t echniques and a star-triangle transformation method. In particular, th e critical exponent of the surface magnetization is found to be close to that of the perfect model, beta(1) = 1/2. The crossover from surfac e to bulk critical properties is discussed.
