Abstract
Nonlinear response of the magnetization respect to slowly changing magnetic field gives random noise, i.e., the Barkhausen noise, which is measured on Fe-Si and permalloy. Analysis of the experimental data shows that the Barkhausen noise has a fractal structure of low dimension between 0.7 and 1.3.
