Magnetic aftereffect phenomena ale simulated in the framework of phenomenological models of hysteresis by using the Monte Carlo technique It is shown that a log t-type dependence of the average value of the output vat able (usually the magnetization) can he qualitatively predicted by using simplified models of hysteresis with local memory. such as the Jiles-Atherton. Hodgdon, or the Energetic model These models are computationally much more efficient than the more elaborate models of hysteresis with global memory like the Preisach model Numerical results related to the decay of the output variable as of functio
