Synthesis and properties of charge-ordered thallium halide perovskites, CsTl1+0.5Tl3+0.5X3 (X = F, Cl)- theoretical precursors for superconductivity?
M. Retuerto, T. Emge, J. Hadermann +14
Recently CsTlCl3 and CsTlF3 perovskites were theoretically predicted to be potential superconductors if they are optimally doped. The synthesis of these two compounds, together wit…
Temperature Dependent Local Structure of LaFeAsO_{1-x}F_x: Probing the Bond Correlations
T. A. Tyson, T. Wu, J. Woicik +6
The local structure of the parent and doped LaFeAsO1-xFx (pnictide) compounds were studied by x-ray absorption spectroscopy. In the doped system, the Fe-As and Fe-Fe correlations a…
X-ray absorption spectroscopy measurement on the LaO1-xFxFeAs system
A. Ignatov, C. L. Zhang, M. Vannucci +5
Results of Fe K-, As K-, and La L3-edge x-ray absorption near edge structure (XANES) measurements on LaO1-xFxFeAs compounds are presented. The Fe K- edge exhibits a chemical shift…
X-ray absorption study of Ti-activated sodium aluminum hydride
J. Graetz, A. Y. Ignatov, T. A. Tyson +2
Ti K-edge x-ray absorption near edge spectroscopy (XANES) was used to explore the Ti valence and coordination in Ti-activated sodium alanate. An empirical relationship was establis…
Superconductivity near the vibrational mode instability in MgCNi3
A. Ignatov, S. Y. Savrasov, T. A. Tyson
To understand the role of electron-phonon interaction in superconducting MgCNi we have performed density functional based linear response calculations of its lattice dynamica…
