Universality classes and crossover scaling of Barkhausen noise in thin films
Lasse Laurson, Gianfranco Durin, Stefano Zapperi
We study the dynamics of head-to-head domain walls separating in-plane domains in a disordered ferromagnetic thin film. The competition between the domain wall surface tension and…
Avalanche Spatial Structure and Multivariable Scaling Functions; Sizes, Heights, Widths, and Views through Windows
Yan-Jiun Chen, Stefanos Papanikolaou, James P. Sethna +2
We introduce a systematic method for extracting multivariable universal scaling functions and critical exponents from data. We exemplify our insights by analyzing simulations of av…
The role of stationarity in magnetic crackling noise
Gianfranco Durin, Stefano Zapperi
We discuss the effect of the stationarity on the avalanche statistics of Barkhuasen noise signals. We perform experimental measurements on a FeB amorphous ribbon and…
Signature of effective mass in crackling noise asymmetry
Stefano Zapperi, Claudio Castellano, Francesca Colaiori +1
Crackling noise is a common feature in many dynamic systems [1-9], the most familiar instance of which is the sound made by a sheet of paper when crumpled into a ball. Although see…
Shape of a Barkhausen pulse
F. Colaiori, S. Zapperi, G. Durin
The average shape of the pulse in Barkhausen noise has been recently proposed as a tool to compare models and experiments. We compute theoretically the pulse shape of Barkhausen no…
Ground state optimization and hysteretic demagnetization: the random-field Ising model
Mikko J. Alava, Vittorio Basso, Francesca Colaiori +4
We compare the ground state of the random-field Ising model with Gaussian distributed random fields, with its non-equilibrium hysteretic counterpart, the demagnetized state. This i…
