Abstract

Un material magnético de ferrita que comprende una fase primaria de una ferrita hexagonal de tipo magnetoplumbita, la fase primaria teniendo una composición representada por la fórmula (I), puede proveer propiedades magnéticas mejoradas en términos de la densidad de flujo magnético residual (Br), fuerza coercitiva intrínseca (iHc), cuadratura (Hk/iHc) y producto de energía máxima (B.Hmáx). Por lo tanto, un un imán permanente de tipo segmento derivado del mismo se puede usar en la fabricación de motores de tipo pequeño para automóviles, motores para equipos eléctricos, así como para electrodomésticos y otros dispositivos.
