摘要：
Double perovskite system, Sr2NiMoO6-delta, was synthesized via facile sol-gel technique. Phase investigation of the prepared sample was carried out employing powder X-ray diffraction technique, which confirmed the single phase formation. The Rietveld analysis of the Sr2NiMoO6-delta revealed tetragonal crystal geometry at room temperature with space group 14/m. A well crystalline single phase of Sr2NiMoO6-delta was obtained by sintering of the powder at 1573 K. Frequency and temperature dependent electrical conductivity of the prepared sample revealed that the conduction behavior followed hopping mechanism of the mobile charge carriers. The XPS spectra of the investigated system indicated the presence of different valence state of Mo (Mo5+ and Mo6+).
