Doping Barium Ferrites Thin Films and Deposition Fe2O3 on Glass with Annealing (950°C) and Study Their Optical Properties

The series of ferrites samples doped by Barium with general formula Barium nitrate Ba(NO3)2  was prepared,  The Chemical Spray Pyrolysis (CSP)technique method of preparation of thin films for Iron (III) nitrate  Fe(NO3)3.9H2O  at (X) values ranging from 3% to 7%, where (X) represents the proportion of Barium in ferrite. doping, as well as the factors affecting the preparation of these films, sintering temperature (950°C)  has been used which is (450oC temperature the substrate). (Network analyzer device) has been used to study the microwaves absorption in the range of (X- band) with a frequency range (8 -12.5 GHz). Also X-ray diffraction analysis (XRD) has been used to determine the crystal structure and purity of the prepared samples and to calculate the average grain size and micro strain, The samples were examined using a scanning electron microscope device to evaluate the crystal size and to see distribution style after the sintering process, Also the resonance peaks for all types of ferrite appeared at frequencies frequencies (8.405, 10.273,11.600) GHz respectively.
