Abstract

La presente invención produce un material magnético de ferrita que tiene un producto energético máximo (BH) máx) notablemente más alto que un material magnético de ferrita convencional mediante la inducción de una magnetización de saturación alta y un campo magnético anisotrópico alto al agregar Co y Zn simultáneamente para sustituir algo de Fe y al ajustar la relación de contenido de Zn/Co. Además, la presente invención puede producir un material magnético deseado a un costo menor que un material magnético de ferrita a base de CaLaCo convencional sustituido solo por Co usando Zn, que es relativamente al menos siete veces más barato que Co, junto con Co.
