Abstract: We present exact results for the critical behaviour of the random field Ising model on complete graphs and trees, both at equilibrium and away from equilibrium, i.e. models for hysteresis and Barkhausen noise. We show that for stretched exponential and power law distributions of random fields the behaviour on complete graphs is non-universal, while the behaviour on Cayley trees is universal even in the limit of large co-ordination.
