Hybridized and Localized 4f Electronic States of Nd-based Intermetallic Compounds in Cubic Symmetry Probed by High-Energy Photoemission
We have performed soft and hard X-ray photoemission spectroscopies on NdTi2Al20 and NdBe13 which show antiferromagnetic ordering at low temperatures. The Nd 3d core-level photoemission and Nd 3d-4f valence-band resonant photoemission spectra show finite 4f4 initial-state components in addition to the 4f3 configurations attributed to the c-f hybridization effects in NdTi2Al20, while the 4f3 initial-state components with localized character are dominant in NdBe13. These results imply the emergence of overscreening channel due to the two-channel Kondo effect in NdTi2Al20 through the the strong c-f hybridization effect.
