Abstract

We have carried out the measurement for a pyrochlore-type Mo oxide (Sm ₂Mo₂O₇) by means of hard-x-ray and soft-x-ray photoemission spectroscopy (PES) with high energy resolution. The PES spectrum obtained with the hard x-ray clearly shows a coherent part and a incoherent part. And its boundary is relatively distinguishable. The ratio of the coherent part to the incoherent part is more enhanced in the hard-x-ray PES compared to the soft-x-ray PES. The results indicate that hard-x-ray photoemission spectroscopy (HAXPES) is powerful method for investigating the bulk electronic state.
