Abstract

Ferrites are usually non-conductive ferrimagnetic ceramic compound materials which contain oxygen and at least two magnetic ions in order to produce spontaneous magnetization, having chemical formula (AB2O4), where A and B represent various metal cations. 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 5% and 7%, where (X) represents the proportion of Barium in ferrite. doping, as well as the factors affecting the preparation of these films, which were deposited on glass Many techniques are used to analyze and test the prepared, sintering temperature has been used which is (450ºC temperature the substrate), to determine the effect of sintering temperature on the final specifications of the samples, (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.
