    • Interplay between coarsening and nucleation in an Ising model with dipolar interactions 

      Cannas, Sergio A.; Michelon, Mateus Fontana; Stariolo, Daniel Adrian; Tamarit, Francisco A. (2008) [Journal article]
      We study the dynamical behavior of a square lattice Ising model with exchange and dipolar interactions by means of Monte Carlo simulations. After a sudden quench to low temperatures, we find that the system may undergo a ...

    • Ising nematic phase in ultrathin magnetic films : a Monte Carlo study 

      Cannas, Sergio A.; Michelon, Mateus Fontana; Stariolo, Daniel Adrian; Tamarit, Francisco A. (2006) [Journal article]
      We study the critical properties of a two-dimensional Ising model with competing ferromagnetic exchange and dipolar interactions, which models an ultrathin magnetic film with high out-of-plane anisotropy in the monolayer ...
