Figure 1
Whole powder pattern determined by the first MPF analysis of the synchrotron powder diffraction data of Sm2Ti2S2O4.9 at 299 K. (Inset) Enlargement of pattern. Plots (red crosses) denote observed data, green lines denote calculated profiles and blue lines denote the difference. Vertical black lines indicate the positions of possible Bragg peaks of the tetragonal I4/mmm Sm2Ti2S2O4.9 phase. This figure is in colour in the electronic version of this paper. |
