Exponential equilibration by slow cooling in the planar random-anisotropy magnet: experiments and simulations
Donald R. Taylor, Orlando V. Billoni, Sergio A. Cannas +1
Neutron measurements of the equilibration of the staggered magnetization in DyAs(0.35)V(0.65)O4 are compared with Monte Carlo simulations of spin dynamics in a planar random-anisot…
Comment on ``Phase transitions in a square Ising model with exchange and dipole interactions'' by E. Rastelli, S. Regina and A. Tassi
Sergio A. Cannas, Mateus F. Michelon, Francisco A. Tamarit
We discuss numerical results presented in a recent ppublication about the critical properties of a two dimensional Ising model with exchange and dipolar interactions.
Human and computer learning: An experimental study
Alexandra C. Tsallis, Constantino Tsallis, Aglae C. N. de Magalhaes +1
Simple memorizing tasks have been chosen such as a binary code on a matrix. After the establishment of an appropriate protocol, the codified matrices were individually presented to…
Metastable states in ultrathin magnetic films
Pablo M. Gleiser, Francisco A. Tamarit, Sergio A. Cannas
The equilibrium phase diagram of a two-dimensional Ising model with competing exchange and dipolar interactions is analyzed using a Monte Carlo simulation technique. We consider th…
