Abstract
A series of non-stoichiometric amounts of SrBaFexMo2−xO6 (x = 1.0, 1.2, 1.3, 1.4 and 1.5) (SBFMO) double perovskite samples have been prepared by conventional sol-gel method. The samples were subjected to X-ray diffraction studies and are found to crystallize in cubic structure with a space group . Using X-ray diffraction data, the lattice parameters and the unit cell volume were determined and found to decrease with increase in content of Fe. Porous nature of materials has been studied using Scanning Electron Microscopy technique (SEM). Energy Dispersive X-ray Spectroscopy (EDS) of the present samples showed that Sr, Ba, Fe, Mo and O elements are present in the samples and non-existence of other impurities elements. The absorption bands observed in the range 400-1000 cm−1 of Fourier Transform Infrared (FTIR) spectra indicates the presence of FeO6 and MoO6 octahedra and also confirms the formation of the double perovskite phase.
