Figure 7
Normalized angular distortion Σ of [(M1)Si6] and [□(M2)6] octahedra as a function of temperature in (a) Mn3Fe2Si3 and (b) Mn5Si3 based on data from Gottschilch et al. (2012). (c) Normalized distance distortion Δ of [(M1)Si6] and [□(M2)6] octahedra as a function of temperature in Mn5Si3 based on data from Gottschilch et al. (2012) (values are normalized to the volumes at 300 K). Estimated standard deviations are smaller than the size of the symbols. Temperatures of the AF1–AF2 and AF2–PM transitions are indicated by dashed lines. |
