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…
