Abstract:
Ab-initio band structure calculations for EuPd 3B x combined with XRD and XAS measurements for different B contents as well as under high pressure were conducted. The results obtained a subtle interplay between doping and volume effects on the valence instability, whereas the disorder is less relevant. With this calculational approach, a stable Eu 2+ valence in Eu 0.4La 0.6Pd 3 due to the La insertion was observed.
