CBED contrast in the lower order Laue zone.
Contrast in a systematic arrangement of lower order Laue zone (LOLZ) beams is reported and analysed using a Bloch wave description. Observations are reported for hexagonal barium ruthenium zirconate (Ba4Ru3ZrO12) and barium ruthenium titanate (Ba3Ti2RuO9), both near the c-axis orientation. The specific scattering dynamics invoked by this diffraction geometry may have novel uses in the exploration of crystallographic parameters.
