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,…

Oxygen Content and Valence of Ru in RuSr2(Gd0.75Ce0.25)2Cu2O10(Ru-1222) Magnetosuperconductor
V. P. S. Awana, M. Karppinen, H. Yamauchi +3
The valence of Ru was analyzed for two RuSr2(Gd0.75Ce0.25)2Cu2O10 samples with different oxygen contents by Ru LIII edge x ray absorption near-edge structure (XANES) spectroscopy.…
