Microscopic foundations of the Rayleigh law of hysteresis
Stefano Zapperi, Alessandro Magni, Gianfranco Durin
The hysteresis properties of ferromagnetic materials at low field are described by the Rayleigh law. We analyze the problem in light of modern statistical mechanics models of hyste…
Low field hysteresis in disordered ferromagnets
Lorenzo Dante, Gianfranco Durin, Alessandro Magni +1
We analyze low field hysteresis close to the demagnetized state in disordered ferromagnets using the zero temperature random-field Ising model. We solve the demagnetization process…
Dipolar random field Ising model: an application to garnet films
Alessandro Magni, Gabor Vertesy
The dipolar-random field Ising model (DRFIM) recently introduced displays a behaviour that can be connected to the magnetization of bidimensional magnetic media. Epitaxial magnetic…
Hysteresis properties at zero temperature in the Dipolar-Random Field Ising Model
Alessandro Magni
We present a modified two-dimensional random field Ising model, where a dipolar interaction term is added to the classic random field Hamiltonian. In a similar model it was already…
