Resumen
Actualmente uno de los materiales magnéticos más utilizados en aplicaciones tecnológicas, son los imanes permanentes (IP) o materiales magnéticamente duros. En vista de su importancia, presento en este trabajo una revisión del estado del arte sobre estos materiales, partiendo de una revisión teórica de los conceptos y características más importantes que deben tenerse en cuenta para entender cómo funcionan; pasando por exponer y discutir los diferentes tipos de materiales que se utilizan en su fabricación y sus aplicaciones industriales relevantes; y finalmente discutir las rutas investigativas actuales y futuras en estos materiales, con el fin de obtener materiales para IP con mejores rendimientos y con menores costos. © 2016.
