- Abstract
Abstract: Manganese dioxide and Ba2Co2Fe12O22 added Ni0.8Zn0.2Fe2O4 ferrites were prepared by solid state reaction process. The structure and magnetic properties of the ferrites were investigated by X‐ray diffractometer and magnetic flux density‐magnetic field analyzer. It was found that the magnetic loss shows increase‐decrease‐increase variation trend with the increase of manganese dioxide additive concentration, and the optimal concentration of manganese dioxide doping is about 1.2 wt.%. Compared with the sample without manganese dioxide doping, further investigation revealed that the hysteresis loss coefficient and eddy current loss coefficient decreased in 1.2 wt.% manganese dioxide doping nickel zinc ferrite, but the residual loss coefficient increased with manganese dioxide doping.
