Abstract
Mn0.4Ni0.6Fe2O4 nanoparticles synthesized by evaporation and auto-combustion methods were studied. The structural properties of prepared and annealed samples were analyzed by X-ray diffraction (XRD). The annealing temperature played a major role in the structural and phase composition, which indicates that the annealed sample contains some secondary phase. The microstructure and particle size of the annealed samples were analyzed by TEM. The dielectric properties were measured using impedance analyzer in the frequency range 1–5 MHz. The effect of particle size with the impact of annealing temperature on the dielectric properties is also analyzed. The prepared nanoparticles were subjected to the gas sensor measurement for different aspects. Liquefied petroleum gas sensing investigations of the prepared samples demonstrate that the sample prepared by auto combustion method possesses an improved response than the sample prepared by evaporation method.
