POWGEN PDF data measured using the high-intensity guide from a 6.4 g sample of BaTiO3 for a total measurement time of 2.5 h and generated with a Q range of 1–30 Å−1. Qdamp and Qbroad for 1–100 Å are 0.0118 and 0.0148 Å−1, respectively. Refinement results are shown for (a) a 1–100 Å fit using a tetragonal P4mm crystal structure as a model (Rwp = 6.68) and (b) a 1–8 Å fit using a rhombohedral R3m crystal structure as a model (Rwp = 4.12). Data are shown as circles, refinement results are shown as colored lines, and the difference curves are shown as solid green lines offset below the data and fits for clarity. |
