Method of production of a cubic manganese-zinc ferrite, which with respect to the stoichiometric composition, contains a slight excess of iron, characterized by the fact that in the reaction mixture for the production of ferrite, a slight amount of manganese and/or zinc is replaced by an amount of monovalent copper such that this amount, expressed as a percentage by weight of cu 2 o, of the total amount of metals converted to the oxides fe 2 o 3 mno, zno and cu 2 o is between 0.2 and 5.
