Abstract

Brkhausen Noise, suploops, demangnetization curves and disorder induced critical behavior, and field sweep rate were discussed. The occurrence of critical point in subloops in the Random field Ising model (RFIM) was also discussed. It was suggested that RFIM also predicts disorder induced critical behavior in the demagnetization curve, or initial magnetization curve and the associated Brakhausen Noise. It was also suggested that ferromagnetic materials with a remanent magnetization can be demagnetized by applying and oscillating magnetic field with amplitude slowly decreasing form a large initial value to zero.
