EFFECT OF DIVALENT IONS SUBSTITUTION ON SOME PHYSICAL PROPERTIES OF COPPER FERRITE

Ferrites are interesting materials from the academic point of view. Also according to the technical point of view, ferrites are involved in many industrial applications. Ferrites properties can be adjusted and strongly changed according to many parametersCu1-x Nix Fe2O4 ferrite system was synthesized for X = 0.0, 0.1, 0.3, 0.5, 0.7, 0.9 and 1.0 utilizing the standard double sintering ceramic technique. From the X-ray investigation the structure of the ferrite was determined and found to be cube structure Cation distribution of the form (CuyFez-y) [Cu1-x-yNixFe2-z+y] O42- was predicted and tried employing two different independent techniques. A comparison between the experimental lattice constant and calculated lattice constant taken from the predicted catConcerning the electrical properties of Cu1-x Nix Fe2O4 ferrite, the DC conductivity was measured at room and elevated temperatures up to ~ 800 K. Structural and magnetic transitions were manifested in the DC measurements. According to the magnetic transiFor technical applications, the dielectric properties of Cu1-x Nix Fe2O4 ferrite system were scrutinized throughout this study. Dispersive trend was detected in the frequency dependence of the dielectric constant `, in the low frequency region. Such disp
