Figure 2
Observed (+) and calculated (gray line) X-ray diffraction profiles for Ag3.4In3.7Sb76.4Te16.5 (crystallized into an A7-type single structure) at 545 K by four-dimensional Rietveld analysis in the commensurate case. A difference curve (observed − calculated) appears at the top of the figure; reflection markers are indicated by vertical spikes below the diffraction patterns: the longer ones are for the peaks of the main reflections and the shorter ones for the satellites. |
