Simulation of hysteresis for ±J triangular lattices

摘要: Abstract We report Monte Carlo simulations of low-temperature hysteresis ±J Ising triangular lattices. A loop similar to the one shown by real spin glasses is found. Such divided in six sectors, according coordination number. Average curves, obtained over large numbers randomly prepared samples, are discussed for different values temperature (T): it found that disappears T⩾2.2J. Characteristics zero-temperature curve explained probabilistic analysis.
