Abstract: In this research, the effect of Zn on the structural, optical and magnetic properties of the Ferrite-copper films Cu1-xZnxFe2O4(CZF) precipitated on quartz glass substrate of x = 0, 0.5, 0.9 thickness of 450±10 nm and prepared by pyrolysis chemical spray method (400±10°C) and annealing (520°C) for 4h, through the X-ray diffraction spectrum. The crystalline structure of the prepared films was determined tetragonal spin ferrite in peak (211) and when it was doping with zinc, it turned into (cubic) in peak (311). The particle size found to decrease by increasing the concentration of Zn. The optical properties of the films were increased in the length of the energy gap before doping (2.74 eV) the energy gap increased by increasing doping to 2.88 eV when (x = 0.9). Typical values of magnetization and coercive force of the CZF films have been found to be Ms = 24.130 emu cm-3 and Hc = 260 Oe, respectively.
