(a) Section of the Rietveld refinement results for BCZN-b using a single BCZN phase. (b) Results using a two-phase model illustrating the contribution from each phase to the overall profile. Phase 1 (fully ordered) is shown by the darker dotted line and phase 2 (partially ordered) is shown by the lighter dotted line.
Results of Rietveld refinement of the neutron time-of-flight data at backscattering for BCZN-b. The observed data are shown as circles, the fit calculated from the model as a solid line, and the difference profile is given below. Tick marks indicate the calculated position of the Bragg reflections. The corresponding -spacing range is . Inset: diffraction profiles recorded in the 30° detector bank showing the (100) BCZN supercell peak and the 8-1-6 impurity phase peak and the calculated positions of Bragg reflection of this phase (lower tick marks). The corresponding -spacing range is .
Dielectric and material properties, unit cell parameters, and order parameters for the (BCZN) samples.
