| Outline of Final Research Achievements |
The electronic structures of UX3 (X=Al, Ga, and In) compounds, which exhibit various magnetic properties, have been studied by the photoelectron spectroscopy with synchrotron radiation to understand the relationship between the magnetic property and the electronic structure in the strongly correlated f- electron system. We have found that 5f electrons have an essentially itinerant character in UAl3 and UGa3 while there is a contribution from electron correlation effect in UIn3. Although their Fermi surfaces have similar structures, their fine structures have distinct differences. They are essential information for the understanding in the itinerant f-electron magnets, and contribute their essential understanding.
