Journal of Magnetism and Magnetic Materials 562, 169780 (2022) The spin glasses show intriguing characteristic features that are not well
understood yet, as for instance its aging, rejuvenation and memory effects.
Here a model based on a stretched exponential decay of its magnetization is
proposed, which can describe the main magnetic features of spin glasses
observed in experiments as the time-decay of thermoremament magnetization, the
relaxation of zero field cooled magnetization, the ac and dc magnetization as a
function of temperature and others. In principle, the here proposed model could
be adapted to describe other glassy systems.
