Valence-sensitive Mn Kα hologram patterns χMn(III) and χMn(IV). (a) χMn(III) and (b) χMn(IV) hologram patterns extracted numerically from the experimental holograms using (α, β) = (0.75, 0.55) as determined from Mn absorption spectra. Calculated (c) χMn(III) and (d) χMn(IV) holograms with 〈u2〉Rel = 0.35 Å2. The FS directions of neighboring Mn and Ca atoms were calculated from either χMn(III) (Mn1D and Mn4A sites) or χMn(IV) (Mn2C and Mn3B sites) emitters and are indicated by the purple (Mn) or green (Ca) circles. |
