| Outline of Final Research Achievements |
We performed angle-resolved photoemission spectroscopy measurements with synchrotron radiation on EuPtP, EuNi2P2, and YbInCu4. From the electronic structure near the Fermi level, we revealed that the presence of an energy gap at the crossing point of the localized 4f and conduction bands. The shape of bands is described by a hybridization-band picture based on the periodic Anderson model. Our results indicate that the c-f hybridization effect in the rare-earth compounds is relevant to the valence transition and heavy-fermion state.
