Abstract

The charge ordered state in Yb₄As₃ has been studied by a resonant x-ray scattering (RXS) technique near the Yb L₃-edge. The anomalous scattering factors, f′ and f″, of Yb³⁺ and Yb₂₊ have been determined using the absorption spectrum of the Yb₄As₃. Based on the anomalous scattering factors, the valences of the two inequivalent Yb sites, +2 25 -δ and +2 25 + 3δ, have been evaluated by the RXS intensity corresponding to the charge ordering. The fully charge ordered state of δ = 0 25 ± 0 02 was elucidated.
