Figure 4
(a) One-dimensional translation scans of the diffraction intensity along the a axis across the periodically domain-inverted region, at energies E = 4.96 and 5.007 keV; note that the intensities below and above the edge are modulated in antiphase to each other. (b) Domain fraction (from 0 = domain `B' to 1 = domain `A') extracted from the ratio of intensities above. Inset: reconstruction of the (417) satellite reflections in reciprocal space induced by the periodic modulation of the domain fraction calculated above. The intensity (in log scale) is plotted against the shift in position along a* relative to the central value h0 = 4. |
