Rietveld refinement and dielectric relaxation of a new rare earth based double perovskite oxide: BaPrCoNbO6

Rietveld refinement plot for BPCN. Inset shows the schematic presentation of the BPCN tetragonal unit cell. The Co2+ atoms are located at the centers of the CoO6 (blue) octahedra. The Nb5+ atoms are located at the centers of the NbO6 (green) octahedra.
