A detail structural and electrical analysis of a few doubleperovskite (La2CoMnO6, La2FeMnO6) and their perovskite counterpart (LaCoO3, LaCrO3and LaFeO3) have been performed. All the compounds are synthesized by wet chemical route(especially by sol-gel & pyropheric route). From XRD data analysis, the samples are found to be in single phase and stoichiometric. The information about the molecular bonding is obtained from the FTIR spectra. The band gap is calculated from UV-Visible spectra and the sample is characterised whether it is semiconducting and insulating. The morphology of the materials has been studied through FESEM and finally the dielectric spectroscopy has been carried out for all compounds
