| Research Abstract |
The ordered states such as magnetism in uranium based compounds have been one of the central issues in condensed matter physics. Especially, the hidden order state observed in Uru_2Si_2 has been attracting much attention for more than 25 years. In the present study, we have performed angle-resolved photoelectron spectroscopy, which is a powerful tool to understand electronic structure of materials, to understand the origin of those ordered states. We have found that U 5f electrons, which are responsible for those ordered states, have an itinerant character. This is very important basis for the understanding of these ordered states.
