Figure 1
Schematic representation of the circular magnetic ordering in CaMn7O12 (view of six unit cells along the modulation vector direction, i.e. the c-axis). The red and green arrows represent the magnetic moments of Mn3+ ions located in the Mn1 and Mn2 sublattices. The nearest neighbours (along c) in the Mn1 and Mn2 sublattices are distant by c/2 (see Table 7). The blue arrows represent the magnetic moments of Mn4+ ions located in the Mn3 sublattice. The nearest neighbours (along c) in the Mn3 sublattice are distant by c. This figure is in colour in the electronic version of this paper. |
