Abstract
Method of manufacturing a magnetic core that has an approximately rectangular hysteresis loop, in which the conditions B r/B cl greater than 0.7 and/or (R s) max greater than 0.6 and H or less 4 Oersted are met, characterized by the fact that a magnetic core s manufactures at least substantially a compound of the formula: Cu x Mn (1-xy) Fe2 O 4 in which x is between 0.05 and 0.2, and is less that 0.7 these compounds being produced by heating a mixture of copper, manganese and iron compounds, in the desired weight ratio in air, or in a gaseous atmosphere whose oxygen content is not higher than that of air, until a temperature between 1350 and 1400ºC.
