Structure and electromagnetic behavior of nanocrystalline in the 8–12 GHz frequency range

Nanocrystalline strontium hexaferrite doped with Zr–Mg is synthesized by the citrate sol–gel process. The cationic site preferences of Mg+2 and Zr+4 in Mg–Zr substituted Sr ferrite were investigated by magnetic measurements and X-ray diffraction (XRD) analysis. Microwave absorption properties have been measured in the frequency range of 8–12 GHz. The results indicate that these ferrite particles have a significant potential for microwave absorption applications in the future.
