Novel structural and magnetic properties of Mg doped copper nanoferrites prepared by conventional and wet methods

Nanoferrites of the general formula Cu1−xMgxFe2O4 with 0≤x≤0.6 were prepared by standard ceramic and wet methods. The structure was studied by X-ray diffraction and IR spectroscopy. The density and lattice constant were calculated and reported. The particle size of the prepared nanoferrites ranged f...

Description
Summary:Nanoferrites of the general formula Cu1−xMgxFe2O4 with 0≤x≤0.6 were prepared by standard ceramic and wet methods. The structure was studied by X-ray diffraction and IR spectroscopy. The density and lattice constant were calculated and reported. The particle size of the prepared nanoferrites ranged from 8.7 to 41.1nm. It was found that the lattice parameter decreases with increasing cation substitution of Mg2+ due to the difference of ionic radius and atomic mass. The dc magnetic susceptibility was measured out using Faraday's method. The magnetic hysteresis measurement was performed using a vibrating sample magnetometer. Magnetic constants such as Curie temperature, effective magnetic moment, saturation magnetization, remanent magnetization and corecivicty were obtained and reported. The magnetic constants decrease with increasing Mg2+, except the remanent magnetization which increased. ► We study the effect of Mg2+ on structural and magnetic properties of copper ferrite prepared by the different methods. ► To determine which method gives the smallest particle size and optimize the physical properties. ► To determine which sample is suitable for different applications.
