| 概要 | We have performed angle-resolved photoemission spectroscopy experiments on paramagnetic UFeGa5 using soft x-ray synchrotron radiation (h nu=500 eV) and derived the bulk- and U 5f-sensitive electronic structure of UFeGa5. Although the agreement between the experimental band structure and the local density approximation calculation treating U 5f electrons as being itinerant is qualitative, the morphology of the Fermi surface is well-explained by the calculation, suggesting that the U 5f states can be essentially understood within the itinerant-electron model. |
