Abstract
The double perovskite compound, La2FeMnO6 (LFMO), has been synthesized using the sol-gel method. Structural properties were characterized by X-ray diffraction (XRD), and X-ray Fluorescence (XRF), Fourier Transform Infrared Spectroscopy (FTIR) and Raman scattering spectroscopy. Rietveld refinement of calcination powder from X-ray data indicates the compound was a single-phase formation of double perovskite with 750 °C and 900 °C calcination temperatures. XRF showed the weight and atomic ratio of the compound are suitable with double perovskite stoichiometric, respectively. The result of structural analysis confirmed that the La2FeMnO6 has a cubic structure with space group Pm-3m at both temperatures. Lattice parameters, volume and crystallite size of the samples become larger as higher calcination temperatures. Raman scattering spectroscopy and FTIR have been used to study the peak vibrational modes and various bond formations of the prepared samples.
