Δρ for YFeO3 and HoFeO3. (a), (c), (e) In the (010) plane through the Fe atoms. (b), (d), (f) In the plane through the intermediate Fe—R (R = Y, Ho) contacts. (a), (b) APD data for YFeO3. (c), (d) APD and (e), (f) SD data for HoFeO3. For atoms deviating from the plane, their deviations are shown in italics. Map borders are 6.6 × 6.6 Å and 8.0 × 6.6 Å. Contour intervals are 0.5 e Å−3 in (a) and (b), and 0.75 e Å−3 in (c)–(f); positive contours, solid lines; negative contours, short dashes. |
