Hard and soft x-ray photoemission spectroscopy study of the new Kondo system SmO thin film
SmO thin film is a new Kondo system showing a resistivity upturn around 10 K and was theoretically proposed to have a topologically nontrivial band structure. We perform hard x-ray and soft x-ray photoemission spectroscopy to elucidate the electronic structure of SmO. From the Sm $3d$ core-level spectra, we estimate …
