High resolution Compton scattering as a Probe of the Fermi surface in the Iron-based superconductor $La{O}_{1-x}{F}_{x}FeAs$

Abstract

We have carried out first principles all-electron calculations of the (001)-projected 2D electron momentum density and the directional Compton profiles along the [100], [001] and [110] directions in the Fe-based superconductor LaOFeAs within the framework of the local density approximation. We identify Fermi surface features in the 2D electron momentum density and the directional Compton profiles, and discuss issues related to the observation of these features via Compton scattering experiments.
