Abstract

Production method of a ferromagnetic body based on an iron-sobalt ferrite, characterized by the fact that a body is manufactured that meets the requirements (R) sub-index s) sub-index max greater than or equal to 0.85 and H sub-index c less 100 Oersted, fusing a mixture, molded to acquire the desired configuration, of at least one cobalt compound and at least one compound of iron oxide (oxide and/or compounds capable of being transformed into oxides) with a composition according with an atomic ratio of Co: Fe between 0.007: 1 and 0.4: 1, under reducing conditions, at a temperature higher than 1200ºC until obtaining a body with a pore volume of no more than 10%, said body being cooled to approximately room temperature and then treated in the known manner by heating it to a temperature higher than 250ºC and then cooling it in a continuous or alternating magnetic field.
