Structural and electromagnetic characteristics of substituted strontium hexaferrite nanoparticles

Substituted strontium ferrite SrFe₉(Mn_0.5Co_0.5Zr)_3/2O₁₉ has been prepared from sol–gel method. X-ray diffraction (XRD), transmission electron microscope (TEM) and vector network analyzer, were used to analyze the structure and dynamic magnetic properties. Powders of sample show a hexagonal fine platelet structure and narrow particle size distribution. Based on microwave measurement on reflectivity, SrFe₉(Mn_0.5Co_0.5Zr)_3/2O₁₉ may be a good candidate for electromagnetic compatibility and other practical applications at high frequency.
