FIELD: metallurgy.
SUBSTANCE: there is prepared charge containing 3-7 wt % of silicon powder, powder of ferrophosphorus at amount facilitating contents of phosphorus in charge not more, than 0.5 wt % and powder of iron as base. Produced mixture is compressed, is subjected to at least one operation of annealing at temperature 1100-1300°C with successive cooling and is sintered in atmosphere of nitrogen gas by cyclic method by alternating annealing and cooling till there are obtained required magnetic properties.
EFFECT: produced material possesses high specific electric resistance and low losses for eddy currents at satisfactory coercion force and magnetisation.
