Figure 5
SANS spectra of 6H-type BaFeO3−δ at 200 K (a), 130 K (b) and 4 K (c). Plus marks are the observed SANS intensities and the solid lines are the calculated ones. Three types of broken lines show the magnetic Bragg peak (00δm), the magnetic diffuse scattering (MDS) and IBASE + IB.G., which is the base function plus the constant background (see text). |
