Abstract
We report EXAFS (Extended X-Ray Absorption Fine Structure) measurement s on three solid solutions of rare-earth monotelluride in order to mea sure the x-dependence of the cation-anion distance and Debye-Waller fa ctor. We find Yb1-xEuxTe is an ideal solid solution with a bimodal dis tribution of distances, accommodated by the Te sublattice, at contrast with the two other solid solutions Pb1-xEuxTe and Yb1-xGdxTe. The ano malous behaviour of the EXAFS parameters in the last system is related to the shallow nature of the Gd donor. (C) 1997 Elsevier Science S.A.
