Dielectric relaxation of the double perovskite oxide BaPrRuO.

Samples of BaPrRuO were prepared by the solid state reaction method and the structure was characterized by X-ray diffraction (XRD). Scanning electron microscopy (SEM) and dielectric measurements were performed in order to investigate the morphology and electric properties of the ceramics. X-ray diffraction data reveal that the BaPrRuO samples are of the cubic crystal structure with the space group 3̄ at room temperature.
