Figure 7
Observed (cross symbols) and calculated (solid line) high-resolution X-ray powder diffraction intensities in a selected angular interval for Ba2FeReO6 at (a) 14 K with the Rietveld refinement performed under a tetragonal model (space group I4/mmm), and (b) 400 K with the refinement under a cubic model (space group Pm[\bar3]m). The difference profiles are also given. Short vertical bars correspond to the calculated Bragg peak positions. The wavelength was λ = 1.37728 Å. The total collection time for each profile (15° ≤ 2θ ≤ 150°) was ∼4 h.
