Abstract
A method capable of calculating long-time magnetization reversal in completely interacting magnetic materials was presented. The low barriers in the systems were overcome by integrating the stochastic Landau-Lifshitz-Gilbert equation. As a result, a more concentrated system at large time scale produced a faster magnetization decay due to more collective magnetization reversal.
