We report on a study of M edges of transition metals and their oxides performed by using high-order harmonics of ultrafast laser pulses and synchrotron radiation. Data of the Mn, Fe, and Co 3p edges demonstrate that laser harmonics in the extreme ultraviolet range are suited for spectroscopy of solids. These results open perspectives for measurements which could in the future be performed in time-resolved mode. Resonant reflectivity of Fe, Co, Fe2O3, and CoO measured at the synchrotron complements the experiment by providing the detailed line shape of the refraction index for reference.

Abstract
We report on a study of M edges of transition metals and their oxides performed by using high-order harmonics of ultrafast laser pulses and synchrotron radiation. Data of the Mn, Fe, and Co 3p edges demonstrate that laser harmonics in the extreme ultraviolet range are suited for spectroscopy of solids. These results open perspectives for measurements which could in the future be performed in time-resolved mode. Resonant reflectivity of Fe, Co, Fe2O3, and CoO measured at the synchrotron complements the experiment by providing the detailed line shape of the refraction index for reference.
