Abstract
A structural analysis is performed for the highly disordered monoclinic structure of the ferroelastic low-temperature phase of ε′-Li0.620(3)V2O5 by fitting a calculated intensity curve to the observed X-ray powder diffraction pattern. The one-dimensional disorder can be described in terms of a 3-layers disorder model of Reichweite s = 1, in which a random disorder of monoclinic and orthorhombic layers stacked along [001] is assumed. The monoclinic layers are characterized by a unit layer thickness and translations of +Δy and −Δy parallel to [010], respectively, while the orthorhombic layer is characterized by a layer thickness 1 + Δd and no translation parallel to [010]. The diffraction intensity is calculated after Kakinoki and Komura, taking into account a probability matrix for the occurrence of the different layer types. The best fit to the observed Synchrotron X-ray powder pattern is obtained assuming a coexistence of monoclinic and orthorhombic domains within one crystal in a volume ratio of 90:10.
