Study of the mixed Ising spins (1/2,3/2) in a random crystal field
L. Bahmad, A. Benyoussef, A. El Kenz
We study the magnetic properties of a mixed Ising ferrimagnetic system, in which the two interacting sublattices have spins , and spins , in t…

A Monte Carlo study of random surface field effect on layering transitions
H. Ez-Zahraouy, L. Bahmad, A. Benyoussef
The effect of a random surface field, within the bimodal distribution, on the layering transitions in a spin-1/2 Ising thin film is investigated, using Monte Carlo simulations. It…

Crossover component in non critical dissipative sandpile models
A. Benyoussef, M. Khfifi, M. Loulidi
The effect of bulk dissipation on non critical sandpile models is studied using both multifractal and finite size scaling analyses. We show numerically that the local limited (LL)…
