Figure 5
Modulation of the nearest-neighbour Mn—O—Mn bond angles in CaMn7O12 are shown for Mn1, Mn2 and Mn3 positions in panels a, b and c. The horizontal axis shows the scale in relative units [see equation (1)]. Results obtained from the analysis of synchrotron radiation diffraction data at T = 10 K (see text). This figure is in colour in the electronic version of this paper. |
