Abstract
FeO/Ni0.5Mn0.5Re2O4 nano-composite was prepared using glycine assisted combustion method. The structure, morphology, chemical composition and magnetization of the as prepared composite was studied using X-ray diffraction, infrared spectroscopy, scanning electron micrographs, energy dispersive X-ray and a vibrating sample magnetometer. The structural parameters such as crystallite size, lattice constant, unit cell volume and theoretical density of the constituents of composite (FeO and Ni0.5Mn0.5Re2O4) have been determined. X-ray diffraction:and infrared measurements confirm formation of both Ni0.5Mn0.5Re2O4 and FeO phases. SEM technique was used to investigate the morphology characteristics of the investigated solid. It was found that the as synthesized composite consisted of polyhedron, spongy, homogeneous and fragile materials, Also energy dispersive X-ray technique showed the concentrations of O, Ni, Fe and Mn species involved in the prepared composite specimen from the uppermost surface to the bulk layers indicating to the elements gradient The saturation magnetization (M-s), remanence magnetization (M-r) and coercivity (H-c) of the as synthesized composite Were 71 emu/g, 24 emu/g and 272 Oe, respectively.
