Strontium hexaferrite SrZrxMnxFe12-2xO19 (x = 0.0-0.8) nanoparticles were synthesized by chemical co-precipitation and sol-gel combustion methods. The co-precipitation is found to be more suitable because samples synthesized by this method have a single phase for x = 0.0-0.8 and DC resistivity is also improved by this method, whereas samples synthesized by the sol-gel combustion method have single phase only when x = 0.0-0.4. The dielectric constant and dielectric loss factor are in excellent agreement with DC electrical resistivity data. (c) 2006 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
