Abstract
Método de fabricación de un núcleo magnético que posee un lazo de histéresis de configuración aproximadamente rectangular de modo que se cumplen las condiciones que Br/Bcl sea superior que 07 y/ (Rs)max sea superior que 06 y Hc sea inferior que 4 Oersted caracterizado por el hecho de que es producido un núcleo magnético que consistepor lo menos principalmentede un compuesto de la fórmula: x NiO. (1-x+y)MnO.Fe2O3 en que x está comprendido entre 01 y 08y está comprendida entre 0 y 05 y la suma de x o y es igual o superior que 02siendo producido tal compuesto al calentarse una mezcla de compuestos de níquelcompuestos de manganeso y compuestos de hierroen las relaciones de peso deseadasen una atmósfera gaseosa oxidanteque posee un contenido de oxígeno de 20 o más vol.%hasta una temperatura comprendida entre 1400 y 1475ºC.
