Abstract
In this research, some ferrite compounds with chemical formulas (Mn0.5Zn0.5Fe2O4, Ni0.5Zn0.5Fe2O4) were synthesized. Consecutively in a solid-state reaction method at a temperature of (1000 0 C) for (4 hours), the structural properties represented by the lattice constant (a), the theoretical density (ρ a), the density as a function of X-ray diffraction (ρ x-ray) and porosity p and the grain (D) in terms of the X-ray diffraction technique, as the results showed that all samples have a spin-cubic crystalline structure and that the lattice constant of the model (Mn 0.5 Zn 0.5 Fe 2 O 4) is greater than the two models (Co 0.5 Zn 0.5 Fe 2 O 4 and Ni. 0.5 Zn 0.5 Fe 2 O 4)respectively. The results also showed that the density as a function of the X-ray diffraction technique for the model (, Ni 0.5 Zn 0.5 Fe 2 O 4) is greater than the density of the compound (Co 0.5 Zn 0.5 Fe 2 O 4), which is considered denser than the compound (Mn 0.5 Zn 0.5 Fe 2 O 4) This result will contribute to an increase or decrease in permeability (P) and grain size (D) resulting from the differential trend of Miller coefficients (220) and for all models, as the largest value is for the model(Ni 0.5 Zn 0.5 Fe 2 O 4) while it is smaller for the two values Co 0.5 Zn 0.5 Fe 2 O 4, Mn 0.5 Zn 0.5 Fe 2 O 4, respectively. The surface topography was also studied according to the scanning electron microscope (SEM) technique, while the properties The isolation of all models, represented by the dielectric constant, both real (ε 1) and imaginary (ε 2) It was shown that the amplitude decreases with frequency due to the process of electrical polarization. In addition, energy dispersive X-ray spectroscopy (ADEX) was studied for all samples. The results showed that the percentage of oxygen content is high in all samples, but it is noted that the percentage of zinc is less than the equivalent percentage within the spinel structure. Ferrite. Also, for all models, it was shown that there is an inverse relationship for frequency and amplitude with both the real (ε1) and imaginary (2ε) dielectric constant.
