摘要

Permanent magnets have attracted research interest in the last decades as they are used in a wide range of applications, in consumer electronics, motors, electric generators, and nano-micro scale applications [microelectromechanical systems (MEMS) and nanoelectromechanical systems (NEMS)]. Plastic-bonded magnets (PBMs)-composites with permanent magnetic powder embedded in a polymer binder-are considered among the most innovative methods of manufacturing magnets at lower temperatures than conventional methods. In this framework, plastic-bonded NdFeGaB magnets were prepared through a novel “high-density PBM” approach and their structural and magnetic properties are presented in this paper. High densities of the order 82% of the theoretical estimated density value were achieved opening a new path toward permanent magnets applications.
