Figure 3
Partial X-ray diffraction patterns for Ba₂YNbO₆, Sr₂CrTaO₆ and Sr₂GaTaO₆. All superlattice reflections are of the R-type and no peak splitting is observed in any of the diffraction patterns over their entire 2θ range. Miller indices given above the diffraction data for Sr₂GaTaO₆ are also applicable to Sr₂CrTaO₆.
