Abstract: We study coarsening dynamics in the ferromagnetic random bond Ising model ind = 1; 2. We focus on the validity of super-universality and the scalingproperties of the response functions. In the d = 1 case, we obtain a completeunderstanding of the evolution, from pre- asymptotic to asymptotic behavior.The corresponding response function shows a clear violation ofsuper-universality. Further, our results for d = 1; 2 settle the controversyregarding the decay exponent which characterizes the response function.
