Avalanches in mean-field models and the Barkhausen noise in spin-glasses

, 2010
We obtain a general formula for the distribution of sizes of "static avalanches", or shocks, in generic mean-field glasses with replica-symmetry-breaking saddle points.

Hysteresis and Noise in Stripe and Clump Forming Systems

, 2005
We use simulations to examine hysteresis and noise in a model system that produces heterogeneous orderings including stripe and clump phases. In the presence of a disordered substrate, these heterogeneous phases exhibit 1/f$^\alpha$ noise and hysteresis ...

Application of flaw detection methods for detection of fatigue processes in low-alloyed steel [PDF]

Transport Problems, 2007
The paper presents the investigations conducted in the Fraunhofer Institute (IZFP Saarbrücken) by use of a BEMI microscope (BEMI= Barkhausenrausch- und Wirbelstrom-Mikroskopie or Barkhausen Noise and Eddy Current Microscopy). The ability to detect cyclic

A two dimensional model for ferromagnetic martensites

, 2005
We consider a recently introduced 2-D square-to-rectangle martensite model that explains several unusual features of martensites to study ferromagnetic martensites.

Beyond power laws: Universality in the average avalanche shape

, 2010
We report the measurement of multivariable scaling functions for the temporal average shape of Barkhausen noise avalanches, and show that they are consistent with the predictions of simple mean-field theories.

Direct measurement of antiferromagnetic domain fluctuations

, 2007
Measurements of magnetic noise emanating from ferromagnets due to domain motion were first carried out nearly 100 years ago and have underpinned much science and technology. Antiferromagnets, which carry no net external magnetic dipole moment, yet have a

The role of stationarity in magnetic crackling noise

, 2005
We discuss the effect of the stationarity on the avalanche statistics of Barkhuasen noise signals. We perform experimental measurements on a Fe$_{85}$B$_{15}$ amorphous ribbon and compare the avalanche distributions measured around the coercive field ...
