Figure 8
Selected parts of the neutron powder diffraction patterns of CaCuxMn7−xO12 with x = 0, 0.1 and 0.23 observed at T = 60 K. The indices of the Bragg peaks are given above the plots and the calculated peak positions are indicated as tick marks below the central plot. The symbols N, and relate to the nuclear, magnetic phase and magnetic phase. Part of the CaCuxMn7−xO12 (x = 0.23) pattern between 51.5 and 55° has been removed because of technical problems with the detectors. |
