Query: The Barkhausen effect   We review key experimental and theoretical results on the Barkhausen effect,
focusing on the statistical analysis of the noise. We discuss the experimental
methods and the material used and review recent measurements. The picture
emerging from the experimental data is that Barkhausen avalanche distributions
and power spectra can be described by scaling laws as in critical phenomena. In
addition, there is growing evidence that soft ferromagnetic bulk materials can
be grouped in different classes according to the exponent values. Soft thin
films still remain to be fully explored both experimentally and theoretically.
Reviewing theories and models proposed in the recent past to account for the
scaling properties of the Barkhausen noise, we conclude that the domain wall
depinning scenario successfully explains most experimental data. Finally, we
report a translation from German of the original paper by H. Barkhausen.
