Driving rate effects in avalanche-mediated, first-order phase transitions
Francisco-Jose Perez-Reche, Bosiljka Tadic, Lluis Manosa +2
We have studied the driving rate and temperature dependence of the power-law exponents that characterize the avalanche distribution in first-order phase transitions. Measurements o…
Disorder induced critical phenomena in magnetically glassy Cu-Al-Mn alloys
Jordi Marcos, Eduard Vives, Lluis Manosa +5
Measurements of magnetic hysteresis loops in Cu-Al-Mn alloys of different Mn content at low temperatures are presented. The loops are smooth and continuous above a certain temperat…
Hysteresis and Avalanches in the Random Anisotropy Ising Model
Eduard Vives, Antoni Planes
The behaviour of the Random Anisotropy Ising model at T=0 under local relaxation dynamics is studied. The model includes a dominant ferromagnetic interaction and assumes an infinit…
