Abstract
By means of extensive computer simulations we analyse in detail the tw o-dimensional +/-J Ising spin glass with ferromagnetic next-nearest-ne ighbour interactions. We found a crossover from ferromagnetic to 'spin glass'-like order both from numerical simulations and analytical argu ments. We also present proof of a second crossover from die 'spin glas s' behaviour to a paramagnetic phase for the largest volume studied.
