摘要：

The effect of Mn+2Co+2Ti+4 substitution on microwave absorption has been studied for BaCoxMnxTi2xFe12-4xO19 ferrite-acrylic resin composites, where x varies from 0.3 to 0.5 in steps of 0.1, in frequency range from 12 to 20 GHz. X-ray diffraction (XRD), scanning electron microscope (SEM), vibrating sample magnetometer, and vector network analyzer were used to analyze the structures, electromagnetic and microwave absorption properties. The results showed that, the magnetoplumbite structures for all samples have been formed. Based on microwave measurement on reflectivity, BaCoxMnxTi2xFe12-4xO19 may be a good candidate for electromagnetic compatibility and other practical applications at high frequency.
