Abstract

Método de producción de un núcleo magnético que posee un lazo de histéresis casi rectangular tal que se cumple la condición B= r/B= c1 > 0 7y/o (R= s)max > 0 6 siendo H= c inferior que 4 Oersted caracterizado por el hecho de que se produce un núcleo magnético que consiste por lo menos substancialmente de por lo menos un compuesto de la fórmula **(ver fórmula)** donde Ni= x **(ver fórmula)** donde Mg= (1-x) **(ver fórmula)** Fe= 2 **(ver fórmula)** donde O= 4 en que: x está comprendido entre 0 2 y 0 8 siendo producido dicho compuesto mediante el calentamiento de una mezcla de compuestos de niquel magnesio y hierro en la relación de peso deseada hasta la temperatura de 1375 a 1475ºC en una atmósfera gaseosa que contiene oxígeno en una cantidad superior que 50% en volumen.
