Abstract

Resonant and nonresonant x-ray scattering, combined with x-ray absorption data, are presented on Yb4As3. The nonresonant data allow a detailed determination of the low-temperature crystal structure and its evolution as a function of temperature. Bond-valence-sum calculations are performed and compared with theoretical predictions. Using the structural knowledge, the energy dependence, near the Yb L3 edge, of particular x-ray reflections are calculated and compared with experiment, and the temperature dependence of the charge order is extracted. A united picture of the temperature-dependent crystal structure and charge ordering in Yb 4As3 emerges and is compared with theory.
