Preparation and study of Mg - Zn ferrite Samples for Absorbing of X-Band Waves Using the Solid State Reaction Method

In this research, samples of spinel ferrite of the form Mg0.2 Zn0.8 Fe2O4 has been prepared by the method of solid state reaction (ceramic method ) for absorbing spectrum of X- Band waves with the range of frequencies ( 8-12 ) GHz and study its characteristics using the waveguide device. The values of reflection coefficient, absorption coefficient and attenuation coefficient were calculated for all (3) prepared samples and their sintering temperature ( 1100, 1150, 1200 ) °C. The results were appearance of a number of resonance peaks at x-band frequencies. Further, it was shown that the less values of the reflectivity and highest values of the absorption and attenuation were reached at 1200°C. The results of x-ray diffraction ( XRD ) showed compatibility with standard results except for some secondary phases with the ferrite samples.
