概要 | Angle-resolved photoelectron spectroscopy(ARPES) measurements,were made in the Ce 3d -> 4f resonance energy region for the paramagnetic state of CeRu2Si2, CeRu2(Si0.82Ge0.18)(2), investigate a variation of band structures around the quantum critical point (QCP). The observed band Structures are very similar between CeRu2Si2 and CeRu2(Si0.82Ge0.18)(2). The results indicate that the Ce 4f electrons in the. paramagnetic state have an itinerant character and participate in the formation of energy bands both in CeRu2Si2 and CeRu2(Si0.82Ge0.18)(2), and the change of the band structures in the paramagnetic states should be continuous around the QCP of the CeRu2(Si1-xGex)(2) system.
