XRD and SEM analyses of structural properties of LaxBa1-xMnO3 solid solutions

Complex oxides La0:97Ba0:03MnO3, La0:73Ba0:27MnO3 and La0:5Ba0:5MnO3 were synthesized and their structural properties were studied. The structural investigation of the samples is done by incorporating X-ray diffraction (XRD) and scanning electron microscope (SEM) technique at room temperature. The Rietveld method was successfully used for the analysis of the obtained diffraction spectra. It was determined that these compounds have a perovskite structure. Partial substitutions La -> Ba do not disturb the ideal perovskite structure and the cubic crystal structure with the space group Pm-3m is preserved. Crystallographic parameters, lattice parameters and interatomic distances were determined for each compound. As a result of SEM studies, it was determined that the size of crystallites in LaxBa1-xMnO3 solid solutions ranged from 2 to 10 mu m.
