The compound was prepared from (ZnFe2O4) and (CdFe2O4)The process of mixing the ferrite compounds was done according to the formula (CdxZn1-xFe2O4),The resulted compound was (Cd0.7Zn0.3 Fe2O4).
The compounds (ZnFe2O4) and (CdFe2O4) were prepared by Co-Precipitation method because this method gives a good homogeneity to the powder particles.
XRD and FE-SEM were performed, the results showed that ferrites had a phase-shaped cube and an increase in the concentration of cadmium in the (CdxZn1-x Fe2O4)compound .This result showed an increase in the lattice constant, the rate of crystalline size and the distance between the crystalline surfaces,due to the fact that the ionic radius of the cadmium is greater than the ionic diameter of the zinc, which is (0.83 A°).The images of the electron microscope (FE-SEM) showed an increase in particle size with an increase of concentration of cadmium ferrite in relation to the compound (CdxZn1-x Fe2O4),The components of the ferrite structures prepared by EDS technique were verified, where the ferritecompound (Cd0.7Zn0.3Fe2O4) mixed with the Neoprene (Chloroprene Rubber) (CR) according to weight ratio of (3,6g)of ferrite, after the process of forming rubber paste.
The VNA was investigated for (8-12 GHz).
It was observed that the reflection coefficient was reduced by increasing the fraction of ferrite to (6g) and obtain highly absorbent materials .Where the material behavior varies according to the frequency, as well as the concentration ratio in the ferrite and the quantity of the ferrite with Chloroprene rubber (CR).ThePermeability of (Cd0.7Zn0.3Fe2O4) was calculated as a function of frequency.The real part of the amplitude showed the amount of energy from the external electric field stored in the material.
