Abstract

Production method of a magnetic core that has an almost rectangular hysteresis loop such that the condition B =r/B =c1 > 0 7y/o (R =s) max> 0 6 with H =c being less than 4 Oersted characterized by the fact that a magnetic core is produced consisting of at least substantially at least one compound of the formula ** (see formula) ** where Ni =x ** (see formula) ** where Mg =(1-x) ** (see formula) ** Fe =2 ** (see formula) ** where O =4 where: x is between 0 2 and 0 8 said compound being produced by heating a mixture of nickel magnesium and iron compounds in the desired weight ratio to a temperature of 1375 to 1475ºC in a gaseous atmosphere containing oxygen in an amount greater than 50% by volume.
