Role of Zr-Co substitution at iron site on structural, magnetic and electrical properties of Sr-hexaferrites nanomaterials synthesized by the sol-gel combustion method

► The particle size is found to be 25-50 nm using the simple and economic synthesis method. ► We are able to improve the saturation magnetization, remanence and DC resistivity. ► The synthesized materials are beneficial for recording media and microwave devices.
