Valence state in R 4 As 3 ( R = Yb and Eu) studied by resonant and non-resonant X-ray scattering
The resonant and non-resonant X-ray scattering technique have been applied to the observation of a valence fluctuated (VF) state in R 4 As 3 ( R = Yb and Eu). In Yb 4 As 3 , the resonant signal reflecting a short range order of the charge ordering of Yb ions was clearly found at Yb L 3 -edge in the...
