Abstract

The valence state of UTe2 was studied by core-level photoelectron spectroscopy. The main peak position of the U 4 f core-level spectrum of UTe2 coincides with that of UB2, which is an itinerant compound with a nearly 5 f 3 configuration. However, the main peak of UTe2 is broader than that of UB2, and satellite structures are observed in the higher binding energy side of the main peak, which are characteristics of mixed-valence uranium compounds. These results suggest that the U 5 f state in UTe2 is in a mixed valence state with a dominant contribution from the itinerant 5 f 3 configuration.
