Gilbert ferromagnetic damping theory and the fluctuation-dissipation theorem

The phenomenological Gilbert-Landau-Lifshitz theory of magnetic damping in ordered magnetic materials has long served as the central model employed in the analysis of considerable experimental magnetic resonance data. The problem undertaken here is to formulate the microscopic basis of the model in...
