Table 3. Application of the extended S-FFT algorithm to neutron diffraction data of the perovskite-related compound with unit formula (Bi0.75Sr0.25)MnO3 .
Crystal data: a = 5.499, b = 7.770, c = 5.542 Å, space group Imma, Z = 4. Phase refinement gives a large negative peak for Mn in the E map, as expected for a negative scatterer (Fermi lengths for Bi, Sr, Mn and O are, respectively, 0.853, 0.702, −0.373 and 0.580).
