| Abstract: | Low loss MnZn power feiTites at high frequency were prepared by conventional oxide ceramic process. Influences of Co2O3 additive on the microstructure and magnetic properties of MnZn ferrites were investigated. The results indicated that proper Co2O3 addition could enhance the initial permeability and decrease the power losses in wide temperature range. Owing to its influence on the remanence, proper Co2O3 additive can enhance the DC - bias performance of the MnZn ferrites. |
