Abstract

Method of manufacturing a magnetic core with a substantially rectangular hysteresis loop and consisting of mixed ferromagnetic ferrite material, in which a mass compressed into the desired shape and, if desired, pre-sintered at a temperature below 800º C . and consisting of oxides of lithium, manganese, iron and possibly nickel and/or compounds of these metals that are transformed into the oxides when they are intensely heated, is sintered, characterized in that the relative amounts of the aforementioned metals in the mass Sintered, expressed in mol% of the oxides: Li2O, MnO, Fe2O3 and NiO, are: (see graphic) and that the sintering process takes place at a temperature of 1,200 to 1,400º C in air or in a mixture of air and oxygen.
