Summary

The electrical and magnetic parameters of copper-manganese ferrites with additions of other metal oxides are compared with those of the 0.15 Cu2O·0.2 MnO2·0.5 Fe2O3 ferrite without an addition. The magnetic parameters of the ferrites were determined by the method of oscillography of dynamic hysteresis loops. It was established that the introduction of the oxides Bi2O3, Sb2O3, TiO2 Cr2O3, ZnO, and CaO leads to a substantial improvement of magnetic parameters, while the addition of the oxides BeO, CdO, BaO, Co2O2, SrO, and Al2O3 causes a deterioration of magnetic properties.
