Abstract
The phase pure Copper Ferrite, Zinc Ferrite, and Nickel Ferrite were prepared from oxides of Ni, Cu, Zn, and Fe using traditional ceramic method. X-ray diffraction data were collected and the formation of the spinal phase structure was found. The lattice parameter was found to be 8.441 Å for ZnFe2O4, 8.35 Å for NiFe2O4, and 8.349 Å for CuFe2O4. The Ni0.4Zn0.6Fe2O4 ferrite was sintered at three different temperatures: namely 1100°C, 1200°C, and 1300°C and similar temperature control was applied to Cu0.2Ni0.2Zn0.4Fe2O4 ferrite group. The energy band gap was calculated for Ni0.4Zn0.6Fe2O4 and Cu0.2Ni0.2Zn0.4Fe2O4 and was found to be 3.657 eV and 4.889 eV, respectively. The dielectric properties were investigated over a wide range using impedance spectroscopy and were found to decrease with the increase of frequency. Similar behavior was observed with the sintering temperature. In the same manner, the electric conductivity was found to decrease with the increase of frequency and sintering temperature as well. On the other hand, the electric resistivity was found to increase with both frequency and the sintering temperature.

Magnetite had been known since early times and it has a formula similar to AB2O4, but it was used only in electronics due to its high electric conductivity that reaches 106 Ω−1∙m−1, with magnetic saturation that reaches 4.75 × 105 m/h, Curie temperature of 585 ̊C and very weak eddy currents, which makes it widely applicable in engineering fields [1] [2]
Summary
The oxides of the cube crystals whose formula is AB2O4 make a big percentage of the inorganic materials which have many applications in industry since they. Magnetite had been known since early times and it has a formula similar to AB2O4, but it was used only in electronics due to its high electric conductivity that reaches 106 Ω−1∙m−1, with magnetic saturation that reaches 4.75 × 105 m/h, Curie temperature of 585 ̊C and very weak eddy currents, which makes it widely applicable in engineering fields [1] [2]. Brittle, stable, and have a dark-grey or black color, with other properties, such as small size, light weight and cubic crystal structure. The most common properties of ferrites include high magnetic permeability, high electrical resistance, high permeability to magnetic fields and high resistance to electrical fields [2] [6]
