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 thermoremanent 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.engAcesso RestritoSpin glassesDynamicsComplex systemsA stretched exponential-based approach for the magnetic properties of spin glassesArtigo10.1016/j.jmmm.2022.169780
