【 摘 要 】

The effect of Mn2+Co2+Ti4+ substitution on microwave absorption has been studied for BaCo0.5Mn0.5Ti1.0Fe10O19 ferrite-acrylic resin composites in frequency range from 12 to 20 GHz. X-ray diffraction (XRD), scanning electron microscope (SEM), vibrating sample magnetometer, AC susceptometer and vector network analyzer were used to analyze the structural, magnetic and microwave absorption properties. The results showed that the magnetoplumbite structures for all samples have been formed. Based on microwave measurement on reflectivity, BaCo0.5Mn0.5Ti1.0Fe10O19 may be a good candidate for electromagnetic compatibility and other practical applications at high frequency.
