Abstract:
The structural, morphological, magnetic, dielectric, and gas analyzing properties are studied in CuFe$_{2}$O$_{4}$(Mn–CuFe$_{2}$O$_{4}$) substituted spinel ferrite nanoparticles synthesized via evaporation and automatic combustion. The obtained nanoparticles are established to possess a spherical shape. The smallest size of Mn–CuFe$_{2}$O$_{4}$ ( 9 nm) nanoparticles is achieved at using automatic combustion. X-ray diffraction and Mössbauer spectroscopy reveal that the crystal lattice constant and the Mn–CuFe$_{2}$O$_{4}$ nanoparticle size are larger at augmenting the annealing temperature from 600 to 900$^\circ$С. The dielectric permeability and losses of Mn–CuFe$_{2}$O$_{4}$ nanoparticles are studied at various synthesis conditions and temperatures of annealing. Various aspects of gas sensibility of synthesized Mn–CuFe$_{2}$O$_{4}$ nanoparticles are tested, as well. The maximum response to the presence of liquefied petroleum gas is 0.28 at the optimum working temperature of 300$^\circ$C for Mn–CuFe$_{2}$O$_{4}$ nanoparticles obtained via automatic combustion and it is 0.23 at 250$^\circ$C for deposited nanoparticles.
