Abstract- This paper examines the microwave absorption properties of lithium ferrite powder, ferrite and barium titanate - ions doped with Cu2+ (Li0.32Zn0.26Cu0.1Fe2.32O4). The ferrite powders synthesized by solid-state reaction method and 70% by weight of it mixed with epoxy resin and then the mixture heated. Thermal gravimetric analysis techniques TGA / DTA have been used for characterization of the samples. In addition, the reflection losses of the samples in the microwave region were measured by Vector Network Analyzer method. The results indicate that the amount of absorption for the synthesized materials can reach up to -4 dB.
