Abstract
Laminated, mechanically strong, rare earth, permanent magnets with dielectric layers having increased electrical resistivity and improved mechanical strength suitable for use in high performance, rotating machines comprising sequential laminates of permanent magnet layers and 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.
