Figure 1
Schematic illustration of the MC monoclinic domains. (a) The distortion of the unit cell and the rotation of the SPD. (b) The [111]-viewed stereographic projection, showing the SPDs for domains of tetragonal (red), rhombohedral (green) and monoclinic MC (blue) symmetry. The tetragonal domains (1), (2), (3) correspond to the [100], [010] and [001] SPDs, respectively. Rhombohedral domains (1), (2), (3) and (4) correspond to the [111], , and SPDs, respectively. These directions within the 12 monoclinic domains are further explained in Table 1. |
