Abstract

Method of production of a ferromagnetic material, characterized in that sintering at a temperature between 1000 and 1450º C, preferably between 1200 and 1350º C, is produced from an initial mixture of finely divided metal oxides and/or compounds that are converted into these metal oxides during sintering and/or compounds of two or more of the component metal oxides, a material having a chemical composition corresponding to 2-21 mol% AO 5-45 mol% of Meo 52 - 83 mol% Fe2O3 wherein A represents at least one of the bivalent metals Ba, Sr, Pb and Ca and Me represents at least one of the bivalent metals Fe, Mn, Co, Ni, Zn, Mg, Cu or the bivalent complex (see formula), in such a way that the material consists of at least two ferromagnetic crystalline phases of the series formed by the cubic crystalline structure of the mineral spinel and the hexagonal crystal structures which have a c axis of about 32.8 Å and an a axis of approximately 5.9 Å which have an axis c of approximately 43.5 Å and an a axis of approximately 5.9 Å which have a c axis of approximately 52.3 Å and an a axis of approximately 5.9 Å which have an axis c of approximately 113.1 Å and an a axis of approximately 5.9 Å and having a c axis of approximately 84.1 Å and an axis a of approximately 5.9 Å (Machine-translation by Google Translate, not legally binding)
