Abstract

We discuss which x-ray absorption fine structure (EXAFS) data of binary doped CmIm' compound structures can be unfolded to determine elemental bond distances and the deviations from random configurations due to site preference occupations (SOPs). SOP-deviation estimations can be further confirmed by independent Fourier transform infrared (FTIR) data analysis. The limits and restrictions of our model are presented and discussed.

PACS: 74.70.Dd Ternary, quaternary, and multinary compounds (including Chevrel phases, borocarbides, etc.);
PACS: 78.70.Dm X-ray absorption spectra;
PACS: 87.64.km Infrared.

Key words: multinary alloys, EXAFS, (D type) crystal structures.
