Roughening of domain walls in ttu'ee dimensional random field Ising magnets is investigated at zero temperature using exact combinatorial optimization [1]. Systems are studied up to L 3 = 2163 with the largest systems L > 120 calculated using a parallel version of the min-cut/max-flow algorithm [2].

We introduce a method for the analysis of spin configurations of Ising-type models exhibiting the return point memory. We define a function fH S g ΒΌ gΓ°s H Γ which allows, starting from a spin configuration s H produced by the application of a field history from saturation state, to obtain the set of
We apply the Wang-Landau method to the study of the critical behavior of the three-dimensional random field Ising model with a bimodal probability distribution. For high values of the random field intensity we find that the energy probability distribution at the transition temperature is double peak
