(Top) The 109 experimental RT (29°C) D-LACBED patterns at the Ca3Mn2O7 [110] zone axis corresponding to the spots indicated in Fig. 3(b). All patterns have an angular range of 20 mrad and are normalized to the full intensity range for display. A mirror is present on (001) but not (10), which can be seen in 00h patterns and by comparing Bijvoet pairs and (false colour patterns, bottom). |
