Preparation and study magnetic properties of the spinal ferrite Mg 1 − X Zn X Fe 2 O 4

Abstract

The ceramic techniques were used to prepare spinal ferrite (Mg-Zn) to evaluate and investigate the microwaves absorption at X-band and Ku-band with formula (Mg 1 − X Zn X Fe 2 O 4 ) at x = (0.0, 0.1, 0.3, 0.4, 0.5, 0.6) where x is percentage of zinc in the ferrite. The dimension of samples was used according to the cavity of Network Analyzer System which were 22.6 × 10 × 10 mm to the X-band cavity, then refine them to 15.5 × 10 × 10 mm within in the Ku-band. The resonance peaks appeared at the frequencies 9, 10, 11, 14, 15, 16, and 17 GHz. It was found that the effect of increase sintering temperature increases the values of attenuation and absorbance with best result in behavior of absorbance for the sample Mg 0.6 Zn 0.4 Fe 2 O 4 at the range of X-band. X-ray diffraction results showed that the structure was polycrystalline.
