Abstract
Methods of manufacturing laminated, rare earth, permanent magnets with dielectric layers having increased electrical resistivity and improved mechanical strength suitable for use in high performance, rotating machines comprising sequentially laminating permanent magnet layers with transition and/or diffusion reaction layers; wherein the transition and/or diffusion reaction layers surround sulfide-based dielectric layers, thereby avoiding direct contact between the dielectric layers with permanent magnet layers.
