Abstract :
A micromagnetic model based on magnetization vector dynamics described by the stochastic Landau-Lifshitz-Gilbert (SLLG) equation for the transverse susceptibility (TS) of particulate media is presented. The effect of the amplitude of excitatory ac field and the effect of thermal relaxation is taken into account.
