Abstract
The small dimension (inferior to one micrometer) of the grains of oxydes obtained by chemical precipitation is retained during the processing of the ferrimagnetic part through precise stoichiometry, cold isostatic pressing and sintering under vacuum at a temperature below 1400.degree.C and for a duration shorter than 4 hours.
