Abstract

We study the role of conductivity in the magnetization dynamics of single-domain ferromagnetic particles. Our approach is based on the coupled system of Maxwell’s and Landau-Lifshitz-Gilbert (LLG) equations. We show that the effective LLG equation for a conducting particle contains two additional terms compared to the ordinary LLG equation. One of them is responsible for the conductivity contribution to the damping parameter. When you are citing the document, use the following link http://essuir.sumdu.edu.ua/handle/123456789/33504
