Synthesis of NiCuZn ferrite nanoparticles and microwave absorption characterization

This study aimed at the low temperature synthesis of NixCu0.5−xZn0.5Fe2O4 ferrite nanoparticles using the citrate precursor method and the reflectivity characterization of Radar absorbing materials. The NiCuZn phase obtained at 350 °C by the Rietveld method showed homogeneous nanoparticle formation....
