The position dependence of the Ortho-VIII domain size along a*(A) and along c* (B), obtained from data measured by scanning micro X-ray diffraction, using a 1 micron incident beam on the sample.The Ortho-VIII domain size do have variations which range from light blue to yellow in a region of about 9 micron squares. The same region size has been investigated, using a 300 nm incidence beam on the sample. The Ortho-VIII mapping of the domain size along a* (D) and along c* (E) are shown. Here the variation is more pronounced, indeed, the intense red–yellow peaks in the two-dimensional color map represent locations in the sample with high strength of Ortho-VIII ordering, and dark blue indicates spots of disordered Ortho-VIII domains.
