Abstract
X-ray-absorption fine structure (XAFS) measurements and analysis are presen ted for ZnO and Zn0.1Mg0.9O at different temperatures from 296 K to 760 K a nd from 373 K to 771 K, respectively. The anharmonic effective pair potenti als of the Zn-O bond in these compounds are found from the analysis of the temperature-dependent XAFS data (Stern E A et al 1991 Phys. Rev. B 43 8850) . The influence of the local structure parameters on the anharmonic effecti ve pair potential is studied.
