Hexagonal Manganites—(RMnO3): Class (I) Multiferroics with Strong Coupling of Magnetism and Ferroelectricity
Figure 2
Structure of hexagonal rare earth manganites, RMnO3. (a) View along (110) and (b) view along the c-axis showing only a single layer of MnO5 trigonal bipyramids. The next layer of MnO5 fits above or underneath the voids shown in (b).
