Abstract
Método de fabricación de un núcleo magnético que posee un lazo de histéresis aproximadamente rectangular, en que se cumplen las condiciones B r /B cl mayor 0,7 y/o (R s ) max mayor 0,6 y H o menor 4 Oersted, caracterizado por el hecho de que un núcleo magnético s fabrica de por lo menos sustancialmente un compuesto de la fórmula: Cu x Mn (1-x y) Fe2 O 4 en que x está comprendido entre 0,05 y 0,2 , y es inferior que 0,7 siendo producidos dichos compuestos mediante el calentamiento de una mezcla de compuestos de cobre, manganeso y hierro, en la relación de pesos deseada en aire, o en una atmósfera gaseosa cuyo contenido de oxígeno no es superior que el del aire, hasta una temperatura entre 1350 y 1400º C.
