摘要: In this study, NiCoZn ferrites with the variation of sintering temperature and chemical composition were prepared by coprecipitation. Microstructures Crystal structure analyzed XRD their electric magnetic characteristics LCR meter morphology observed SEM. We identified that these powders have a typical spinel nanoparticles average size 40 nm. The impurity, initial permeability Q factor value are lowest sintered ferrite at . Also, we measured S-parameter for which showed maximum reflection loss -3.1 dB 6 GHz 2 mm thick sample. From result, found can be used in microwave-absorbing application higher frequency region (> GHz).
