Synthesis of BaZn0.6Zr0.6Fe10.8O19 powder samples using sol–gel-auto-combustion method has been reported. The impact of calcination temperature on the structural, magnetic and surface morphology of these samples has been investigated. XRD data confirms that the samples are phase pure and have no traces of intermediate phase such as α/γ-Fe2O3 and BaCO3 etc. The lattice parameters and cell volume increase slightly with increase in calcination temperature. The c/a parameter is <3.98 for all samples implying that they are M-type hexaferrites. Magnetic measurements reveal an increase in the values of coercivity (HC) and saturation magnetization (MS) increase with calcination temperature. The grain size increase from≈100 nm to ≈2 µm with increase in calcination temperature from 800 °C to 1100 °C. [ABSTRACT FROM AUTHOR] |
