Dipolar Interaction Effects in Systems of Macrospins Studied with a Dynamic Stoner-Wohlfarth Model

Abstract

In this paper, we describe the effects of the dipolar interaction on magnetic systems using an original implementation of a Dynamic Stoner-Wohlfarth Model (DSWM) while comparing the results with the widely-used micromagnetic approach based on the Landau-Lifshitz-Gilbert equation. This new model for magnetization dynamics is able to accurately describe time dependent magnetization processes of large systems of macrospins in interaction in a numerically efficient manner with the aim of significantly increase the time range of such simulations.
