| Resumo: | 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. The analysis of particle size and the critical diameter of the domains indicated monodomain formation on nanometric scale. Vibrating sample magnetometry showed that adding copper to NiZn ferrite decreases magnetization saturation and the calcining temperature. Reflectivity measures taken by the wave guide method, obtained absorption radiation of 96.6% for x = 0.3 at 12 GHz. |
