Abstract
Oxidation-state-specific dynamics at the Fe M-2,M-3-edge are measured on the sub-100 fs time scale using tabletop high-harmonic extreme ultraviolet spectroscopy. Transient absorption spectroscopy of alpha-Fe2O3 thin films after 400 nm excitation reveals distinct changes in the shape and position of the 3p -> valence absorption peak at similar to 57
