Study the Structural and Magnetic Properties of (x) Ni0.4Cu0.2Zn0.4 Fe2O4 + (1-x) BaTiO3 Prepared by Solid State Reaction Method
Main Article Content
Abstract
The electrophoretic compounds were prepared with the chemical formula (x) Ni0.4Cu0.2Zn0.4 Fe2o4 + (1-x) BaTiO3, and with weight ratios (x = 0.15,0.30,0.45), by the solid-state method interactions. The prepared samples were annealed at (9500℃) for a period of (4hr). After that, physical examinations were made to it, as well as studying the structural properties of lattice constants (a, c), grain size (DP), density of both types, apparent density (a) and density in terms of x-ray diffraction (x-rayρ), where it was found that it increases with increasing fear phase focus. While the porosity decreases. A scanning electron microscope (SEM) was used to calculate the granular size (Dnn) and study its homogeneity and its role in improving the physical and magnetic properties. EDAX technology has also been used to confirm component ingredients and weight ratios. The residual magnet (Mr) for all samples was calculated according to (VSM) technique.
