The fluorite-related "solid solutions" of CeO2Y2O3 II : A modulated structure approach
The structural description of any particular member of the CeO2Y2O3 solid solution series reduces to the determination of compositional and displacement eigenvectors associated with two sets of modulation wave-vectors. The primary modulations are associated with oxygen (vacancy) ordering and the second-harmonic modulations with metal atom ordering —both with concomitant structural relaxation. Wit
