Polycrystalline Ca0.925Ce0.075Mn0.9Fe0.1O3 were prepared by sol-gel reaction at 1073 K. The compound was analyzed by a powder X-ray diffraction technique and found to be in single phase. The unit-cell parameters and atomic positions were refined using General Structure Analysis to an orthorhombic structure with space group Pnma (#62) a = 5.281 90 (33) Å, b = 7.4968 (45) Å, and c  = 5.302 90 (32) Å.

Rietveld refinement of X-ray powder diffraction data of Ca0.925Ce0.075Mn0.9Fe0.1O3 polycrystalline material

Powder Diffraction

In this present study, nanocrystalline perovskite structure CaMnO3 substituted with Ce and Fe was prepared by a sol–gel technique using citric acid as a chelating agent at 800&nbsp;°C. The compound was analyzed by powder X-ray diffraction technique and found to be single phased orthorhombic perovskite structure with space group Pnma. The morphology of the synthesized material study is carried out by using SEM and EDX confirmed the chemical compositions of the sample. Electrical measurements were performed to determine the conductive nature of the sample, and the conductivity increases with increasing Fe concentration. Electrode polarization effect was apparently seen in the Nyquist plot and the conductivity measurements. Dielectric relaxations were present in the sample was attributed to the existence of oxygen vacancy, migration in the ions and the Ea is calculated using Arrhenius equation. © 2016, Springer Science+Business Media New York.
