High-energy x-ray diffraction studies of \textit{AE}Fe$_{2}$As$_{2}$ compounds
ORAL
Abstract
The relationship between structure, magnetism and superconductivity has become a major theme in studies of the iron arsenide family of superconductors. We have used high-energy x-ray diffraction, together with two-dimensional area detectors, to image large regions of reciprocal space in order to gain further insight into the structural transitions in the \textit{AE}Fe$_{2}$As$_{2}$ (\textit{AE} = Ca, Sr, Ba) compounds. Here we present results of our study of the impact of annealing and temperature on the structure of these materials.
