Abstract

In this paper we are presenting the results of our micromagnetic studies concerning the precessional switching process of the magnetic moment in the presence of a pulsed magnetic field. The magnetization dynamic is calculated with the well-known Landau-Lifshitz-Gilbert equation. We have analyzed the effect of pulse duration and the effects induced by the moment orientation dependent damping term. The results are discussed and compared with the results presented by other authors..

Keywords
