Thin films of Copper- substituted Zinc ferrites as general Zn1-xCuxFe2O4 where (x = 0.0, 0.3, 0.5, 0.7, 0.9) It was prepared using the technique of spray pyrolysis technique on the glass substrate with a temperature equals (400±10oC). High purity of Copper nitrate, Zinc chloride and Iron oxalate were dissolved in 1 mole in de-ionized water. The prepared films are annealed at 520 oC. XRD pattern are used to study the structure of the prepared thin film ferrite. XRD results showed that the prepared thin films Zn1-xCuxFe2O4 are polycrystalline with spinel cubic structure. The results also showed the spinal ferrite structure was modified by the substitute ions. SEM results showed that the prepared films were of a uniform and homogenous nature. Results of thermal reflectivity showed that the reflectivity of the films increases with increasing of (x) and it is approximately greater than 60%. The magnetic properties of the prepared films were examined using Vibrating Sample Magnetometer(VSM). The magnetization measurements indicate that the Zn1-xCuxFe2O4 showed ferromagnetic demeanor at room temperature.
