英文摘要: Mn–Zn ferrites with high initial permeability ( μ i) and high saturation magnetic flux density ( B s) were successfully synthesized by using a conventional ceramic processing route with addition of MoO3. The structure, morphology, magnetic properties, and complex impedance of all samples were investigated by X-ray diffraction, scanning electron microscopy, DC magnetic instrument, and precision LCR meter. The addition of MoO3 promotes the growth of larger and more uniform grains and therefore enhances the μ i. Meanwhile, it improves the density and hence the B s. Through the analysis of complex impedance spectra by an equivalent circuit model, it is demonstrated that MoO3 mainly exists at grain boundaries and...
