Disordered ferromagnetic systems with stochastic driving

Abstract

We study the effects of a newly proposed type of driving conducted by the stochastic increments of the external magnetic field applied to the disordered three-dimensional ferromagnetic systems. The influence of randomness is analyzed in the representative regimes of stochastic driving covering a wide range of driving rates (slow, intermediate and fast). Obtained results are consistent with the experimental ones for the systems exhibiting similar intermittent avalanche dynamics. Stochastic driving opens a more realistic general experimental and theoretical framework for the studies of not (easily) feasible real-world phenomena, with the prospect of becoming a broadly applicable platform going beyond the scope of the nonequilibrium zero-temperature variant of the random field Ising model used here as its exemplification.
