Disorder-Induced Critical Phenomena in Hysteresis: A Numerical Scaling Analysis
Olga Perkovic, Karin A. Dahmen, James P. Sethna
Experimental systems with a first order phase transition will often exhibit hysteresis when out of equilibrium. If defects are present, the hysteresis loop can have different shape…

Avalanches, Barkhausen Noise, and Plain Old Criticality
Olga Perković, Karin Dahmen, James P. Sethna
We explain Barkhausen noise in magnetic systems in terms of avalanches near a plain old critical point in the hysteretic zero-temperature random-field Ising model. The avalanche si…
