Summary of losses in magnetic materials

This is the authors' abstract. We don't add key points for this paper.

Current concepts of the physical origin and mechanisms of losses in magnetic materials are reviewed under three traditional categories: hysteresis losses, eddy-current or dielectric losses, and residual losses. The phenomenological Landau-Lifshitz equation is used to quantitatively express the various manifestations of the residual losses. Possible physical mechanisms contributing to the phenomenologically introduced Landau-Lifshitz damping term are qualitatively discussed.
