Figure 6
Partial projection of the (34)3 hexaferrite structural model corresponding to the MYMY3 sequence. The unit cell contains a threefold repeat of the sequence shown, with subsequent repeats translated in plane by (2/3, 1/3). The tetrahedral (light blue), octahedral (dark blue) and bipyramidal (grey) iron environments are represented. Tetrahedral mixed iron/zinc sites are shown in orange and barium atoms are shown in green. The histogram indicates the proportions of iron (light blue) and zinc (orange) occupancy in the tetrahedral sites. |
