So far, studies have focused on marginal or irrelevant cases of disorder. Using duality arguments, as well as exact Pfaffian techniques we reproduce these analytical estimates. In addition, we obtain different estimates for spin-glass models on hierarchical lattices where the effects of disorder are relevant. We show that the phase-boundary slope near the Onsager point can be used to probe for the relevance of disorder effects. 1742-5468 10.1088/1742-5468/2011/02/P02004 https://hdl.handle.net/20.500.14352/42825 http://dx.doi.org/10.1088/1742-5468/2011/02/P02004 http://iopscience.iop.org https://arxiv.org/abs/1009.6015v2 Universality in phase boundary slopes for spin glasses on self-dual lattices
