Eddy current damping of a moving domain wall: beyond the quasistatic approximation
Francesca Colaiori, Gianfranco Durin, Stefano Zapperi
In conducting ferromagnetic materials, a moving domain wall induces eddy currents in the sample which give rise to an effective retarding pressure on the domain wall. We show here…
Loss separation for dynamic hysteresis in magnetic thin films
Francesca Colaiori, Gianfranco Durin, Stefano Zapperi
We develop a theory for dynamic hysteresis in ferromagnetic thin films, on the basis of the phenomenological principle of loss separation. We observe that, remarkably, the theory o…
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…
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…
Phase transitions in a disordered system in and out of equilibrium
F. Colaiori, M. J. Alava, G. Durin +2
The equilibrium and non--equilibrium disorder induced phase transitions are compared in the random-field Ising model (RFIM). We identify in the demagnetized state (DS) the correct…
The Barkhausen effect
Gianfranco Durin, Stefano Zapperi
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…
