Malarz, K.; Antosiewicz, W.; Karpińska, J.; Kułakowski, K. - In: Physica A: Statistical Mechanics and its Applications 373 (2007) C, pp. 785-795

We investigate the magnetization reversal processes on classes of complex spin networks with antiferromagnetic interaction along the network links. With slow field ramping the hysteresis loop and avalanches of spin flips occur due to topological inhomogeneity of the network, even without any...

The Ising model in a Bak–Tang–Wiesenfeld sandpile

Koza, Zbigniew; Ausloos, Marcel - In: Physica A: Statistical Mechanics and its Applications 375 (2007) 1, pp. 199-211

We study the spin-1 Ising model with non-local constraints imposed by the Bak–Tang–Wiesenfeld sandpile model of self … usual thermodynamic criticality of the two-dimensional Ising model is not affected by SOC constraints (the specific heat … critical exponent α≈0), nor are SOC-induced correlations affected by the interactions of the Ising model. Even though the …

Re-entrant phase transitions of the Blume–Emery–Griffiths model for a simple cubic lattice on the cellular automaton

Seferoğlu, N.; Kutlu, B. - In: Physica A: Statistical Mechanics and its Applications 374 (2007) 1, pp. 165-172

The spin-1 Ising (BEG) model with the nearest-neighbor bilinear and biquadratic interactions and single-ion anisotropy is simulated on a cellular automaton which is improved from the Creutz cellular automaton (CCA) for a simple cubic lattice. The simulations have been made for several sets of...
