Numerical simulation of the aftereffect of a Co/Pt bimodal magneto-optical medium

Moving version of the Preisach-Arrhenius (PA) model function is used to simulate aftereffect in bimodal Co/Pt multilayers. The Co/Pt multilayers are assumed to have two kinds of magnetic phases, each characterized by its own magnetic properties. The Co/Pt bimodal major loop is the sum of the conventional (unimodal) loops of each of the two constituent phases. The aftereffect of each of these loops is calculated separately using its own parameters obtained from the major loop. The individual models are then combined into a single bimodal aftereffect model.
