Abstract

Hysteresis cycles for cubic ± J Ising spin glasses are obtained by Monte-Carlo simulations and compared to similar results previously reported for triangular systems. Generic characteristics, such as hysteresis cycles divided in sectors and no return memory point, are explained in general. A discussion is done for the magnetization within each sector, dissipated energy per cycle and temperature dependence. © 2001 Elsevier Science B.V. All rights reserved.
