Iron and molybdenum valences in double-perovskite (Sr,Nd)2FeMoO6: electron-doping effect
J. Linden, T. Shimada, T. Motohashi +2
Double perovskite, (Sr1-xNdx)2FeMoO6, was doped with electrons through partial substitution of divalent Sr by trivalent Nd (0 < x < 0.2). The Fe valence and the degree of B-site or…

The valence state of iron in the Sr2Fe(Mo,W,Ta)O6.0 double-perovskite system: An Fe K-edge and L2,3-edge XANES study
M. Karppinen, H. Yamauchi, Y. Yasukawa +4
Here we employ both Fe K and L2,3 edge x-ray absorption near-edge structure (XANES) spectroscopy techniques to clarify that iron in the B-site ordered double-perovskite halfmetal,…

Iron valence in double-perovskite (Ba,Sr,Ca)2FeMoO6: Isovalent substitution effect
Y. Yasukawa, M. Karppinen, J. Linden +3
In the Fe-Mo based B-site ordered double-perovskite, A2FeMoO6.0, with iron in the mixed-valence II/III state, the valence value of Fe is not precisely fixed at 2.5 but may be fine-…
