Figure 4
Powder diffraction pattern obtained by integrating the Debye–Scherrer ring of Fig. 3. The cross marks are experimental points and the solid line is a Rietveld fit using the data from 18 to 120° in 2θ; the lower trace shows the difference between the observed and calculated intensities. Tick marks indicate the positions of allowed Bragg reflections. The inset shows the 111 reflection profile. |
