Figure 2
X-ray powder diffraction pattern of BaGeO3 with Cu Kα1 radiation. The high-angle region is shown scaled by a factor of 10 for clarity. Also given are the reflection positions of the main phase and the difference to the calculated pattern. Residuals of the Rietveld fitting are Rwp = 0.042, χ2 = 1.8, RBragg = 0.045. Note that at 13.9 and 36.2° two broad peaks appear, which probably result from some amorphous phase and have been modelled as part of the background. |
