Abstract

Clearly defined Lorentzian-like profiles of the Ortho-II superstructure diffraction peaks have been observed with neutrons for the first time. The superstructure has been refined by simultaneously fitting neutron and x-ray measurements on the same crystal. The combination of both x-ray and neutron information is important since the formation of the Ortho-II phase is driven by oxygen ordering which can be most clearly seen by the neutrons whilst the x-rays are more sensitive to the heavy ion displacements.
