Statistical characterization of Barkhausen noise

Physical Review E, 1994
We investigate whether Barkhausen noise exhibits self-organization and precursor events in the manner of the sandpile models used to illustrate self-organized criticality, and the extent to which Barkhausen noise can be described by single-domain wall pictures.

Granular Shearing and Barkhausen Noise

2007
We present results from a series of experiments on a granular medium sheared in a Couette geometry and show that their statistical properties can be computed in a quantitative way from the assumption that the resultant from the set of forces acting in the system performs a Brownian motion.

Barkhausen noise in relaxor ferroelectrics

SPIE Proceedings, 2003
Relaxor ferroelectrics form a diverse class of materials which typically show cooperative freezing into a nonergodic glassy state without long-range ferroelectric order. We discuss Barkhausen noise techniques in the non-ferroelectric regimes of the relaxors as a probe of the types of glassy order present.

Spectral damping in Barkhausen noise

IEEE Transactions on Magnetics, 1975
The spectral amplitude damping of Barkhausen noise is determined theoretically and experimentally as a function of distance inside the sample itself. Power spectra for noise amplitude and its time derivative are measured in some steel specimens over a wide frequency range. Some examples of the influence of the sample microstructure on the power spectra

Barkhausen noise in fluxgate magnetometers

Applied Scientific Research, 1974
Barkhausen noise is one of the limiting factors for the sensitivity of fluxgate magnetometers. In order to set up calculations about Barkhausen noise, the theory of Bittel and Storm [1] had to be modified. As a result an equation for the signal-to-noise ratio is given, which gives criteria to increase the sensitivity of fluxgate magnetometers.

Use of Barkhausen Noise in Fatigue

NDT & E International, 1989
Barkhausen noise is generated by abrupt changes in the magnetization of materials under applied AC magnetizing field /1/. These changes are known to be affected by residual and/or applied stresses /2, 3/. Monitoring the Barkhausen noise under controlled conditions then provides a means of evaluating the stress state of the material /4/.
