Acesso em: 23 set. 2020.1809-8797https://repositorio.ufrn.br/handle/123456789/30782This paper proposes to investigate the sintering at 1200ºC/2h of Ni0.5Zn0.5Fe2-xSmxO4 ferrite doped with 0.05; 0.075 e 0.1 mol of Sm synthesized by combustion reaction to evaluate the performance materials as absorbers of electromagnetic radiation. The influence of the concentration of samarium on the structure, morphology and electromagnetic properties of ferrites was studied. The resulting samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), magnetic measurements and reflectivity measurements in the frequency range between 8-12 GHz. The results showed that increasing the concentration of samarium caused a decrease in particle size of the samples, encouraging, therefore, to obtain materials with better values of magnetization and reflectivity, allowing for use as absorbers in narrow-band frequency between 9-10 GHzSinterizaçãoMateriais absorvedoresSamárioFerrita Ni-Znarticle
