Structure and electromagnetic behavior of nanocrystalline SrMgxZrxFe12−2xO19 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.
