Abstract

Polycrystalline samples with general formula Yb_2-xCo_x O₃ (0 < x < 0.6), obtained by sol-gel method and analysed by X-ray diffraction, formed solid solutions over all the mentioned range. Co showed a maximum solubility of 30 mol% in Yb₂O₃ sesquioxide. The lattice parameters are found to vary linearly with the composition x. The cationic distribution over the two non-equivalent sites 8b and 24d of the space group Ia-3 is found to be preferentially. Replacing Yb³⁺ by Co³⁺ introduces slight changes in the atomic coordinates leading to an increase of the mean cation-anion distances. The ability of Raman spectroscopy to detect changes in local co-ordination is utilized. A pseudo-tetrahedral coordination for the Co³⁺ in the 24d site was found.

 sesquioxide. The lattice parameters are found to vary linearly with the composition x. The cationic distribution over the two non-equivalent sites 8b and 24d of the space group Ia-3 is found to be preferentially. Replacing Yb<sup>3+</sup>
 by Co<sup>3+</sup>
 introduces slight changes in the atomic coordinates leading to an increase of the mean cation-anion distances. The ability of Raman spectroscopy to detect changes in local co-ordination is utilized. A pseudo-tetrahedral coordination for the Co<sup>3+</sup>
 in the 24d site was found.</EA>
