Figure 1
Results of the Rietveld refinement of the synchrotron radiation powder diffraction pattern of CaMn7O12 at 10 K. The solid points represent measured data, while the solid line represents the calculated diffraction pattern. The step was 0.002°. Below the graph there is a difference curve. The ticks indicate the positions for the Bragg peaks due to the crystal structure of CaMn7O12 (black – fundamental, green – satellite reflections) (top) and two impurity phases: CaMn4O8 (middle) and Mn2O3 (bottom). This figure is in colour in the electronic version of this paper. |
