Force Correlations in Disordered Magnets
Cathelijne ter Burg, Felipe Bohn, Gianfranco Durin +2
We present a proof of principle for the validity of the functional renormalization group, by measuring the force correlations in Barkhausen-noise experiments. Our samples are soft…
Playing with universality classes of Barkhausen avalanches
Felipe Bohn, Gianfranco Durin, Marcio Assolin Correa +4
Many systems crackle, from earthquakes and financial market to Barkhausen effect in ferromagnetic materials. Despite the diversity in essence, the noise emitted in these dynamical…
Universality and the collapse of multifractality in Barkhausen avalanches
Gustavo Zampier dos Santos Lima, Gilberto Corso, Marcio Assolin Corrêa +3
Barkhausen effect in ferromagnetic materials provides an excellent area for investigating scaling phenomena found in disordered systems exhibiting crackling noise. The critical dyn…
Statistical properties of Barkhausen noise in amorphous ferromagnetic films
F. Bohn, M. A. Corrêa, M. Carara +3
We investigate the statistical properties of the Barkhausen noise in amorphous ferromagnetic films with thicknesses in the range between and nm. From Barkhausen noise…
Beyond power laws: Universality in the average avalanche shape
Stefanos Papanikolaou, Felipe Bohn, Rubem L. Sommer +3
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 o…
