Disorder-induced mechanism for positive exchange bias fields
Orlando V. Billoni, Francisco A. Tamarit, Sergio A. Cannas
We propose a mechanism to explain the phenomenon of positive exchange bias on magnetic bilayered systems. The mechanism is based on the formation of a domain wall at a disordered i…
The exchange bias phenomenon in uncompensated interfaces: Theory and Monte Carlo simulations
Orlando V. Billoni, Sergio A. Cannas, Francisco A. Tamarit
We performed Monte Carlo simulations in a bilayer system composed by two thin films, one ferromagnetic (FM) and the other antiferromagnetic (AFM). Two lattice structures for the fi…
Stability as a natural selection mechanism on interacting networks
Juan I. Perotti, Orlando V. Billoni, Francisco A. Tamarit +1
Biological networks of interacting agents exhibit similar topological properties for a wide range of scales, from cellular to ecological levels, suggesting the existence of a commo…
Non-equilibrium structures and slow dynamics in a two dimensional spin system with competitive long range and short range interactions
Omar Osenda, Francisco A. Tamarit, Sergio A. Cannas
We introduce a lattice spin model that mimics a system of interacting particle through a short range repulsive potential and a long range attractive power law decaying potential. W…
Emergent self-organized complex network topology out of stability constraints
J. I. Perotti, O. V. Billoni, F. A. Tamarit +2
Although most networks in nature exhibit complex topology the origins of such complexity remains unclear. We introduce a model of a growing network of interacting agents in which e…
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…
