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 (C) 2010 Elsevier Ltd All rights reserved
