This work presents the synthesis of ferrite with the composition Ni 0.5 Zn 0.5 Fe 2 O 4 ., its investigation by the methods of SEM., TG/DTA., PXRD., FTIR and the preparation of thin composite films using polyvinylchloride (PVC) as the base material and ferrite as fillers. Nickel-zinc ferrite nanopowder with a cubic spinel structure was synthesized by glycine-assisted sol-gel route. From TG/DTA experiment it was found that single phase product was formed already after combustion of dried glycine-nitrate gel. According to X-Ray diffraction and SEM it was determined that ferrospinel after annealing at 650°C during 5 h has a porous structure., homogeneous composition. The crystallite size was approximately 29-31 nm. On the FTIR spectra of oxide-polymer composites showed the presence of a characteristic band of PVC., ferrite and plasticizer. The radio-absorbing properties of the resulting films in the Ka-band were investigated. The microwave studies indicate that radio-transparent composite material was obtained on the basis of PVC/ Ni 0.5 Zn 0.5 Fe 2 O 4 ., with a weak dependence of the reflection value on the concentration of the ferrite filler.
