Effect of Zn content on structural, morphological and magnetic behavior of ZnxCo1-xFe2O4/SiO2 nanocomposites

ZnxCo1-xFe2O4/SiO2 (x = 0, 0.25, 0.50, 0.75, 1.00) nanocomposites (NCs) have been investigated through structural, morphological and magnetic measurements. X-ray diffraction and Mössbauer data indicated the presence of nanocrystalline mixed cubic spinel. The lattice parameters gradually decreased with increasing Zn content and follow Vegard's law. The crystallite size, X-ray density and porosity of ZnxCo1-xFe2O4 decreased with increasing Zn...
