Abstract:
Z-type barium hexaferrite Ba Mno Nio Co 15 Fe 24O4 was synthesized by sol-gel method. Xray diffraction (XRD), Mössbauer spectroscopy, vibrating sample magnetometry (VSM), transmission electron microscope (TEM), electron diffraction and vector network analyzer were used to analyze the structures electromagnetic and microwave absorption properties. The ferritepolymer composites with different ferrite ratios of 50%, 60%, 70% and 80% in polyvinylchloride matrix were prepared. Based on microwave measurements of reflectivity, Ba Mn4NiCo 15 Fe 24O4 is a good candidate for electromagnetic compatibility and other practical applications at high frequencies. It should be noted that thicknesses of the absorbers are only 1.8m.
