Abstract It is well known from theoretical models that a ferromagnetic system should undergo a disorder induced phase transition in its magnetization reversal mode at a critical disorder level R C , below which, the reversal is characterized by the appearance of the so-called spanning avalanche. The critical regime above R C is characterized by power-law distributed avalanche sizes and durations, whose exponents determine the universality class to which the magnetic system belongs. The most… Expand
