摘要:

用芯能级光电子能谱学研究了UTe $_2$的价态。UTe $_2$的U-$4f$核能级谱的主峰位置与UB $_2$的主峰位置一致,UB $_2$是一种具有近似$5f^3$构型的巡游化合物。但是,UTe $_2$的主峰比UB $_2$的主峰宽,并且在主峰的高结合能侧观察到卫星结构,这是混合价铀化合物的特征。这些结果表明,UTePDMATHABMM中的U 5 $f$态是一种混合价态,巡游$5f^3$组态的贡献占主导地位.

英文摘要:

The valence state of UTe$_2$ was studied by core-level photoelectron spectroscopy. The main peak position of the U $4f$ core-level spectrum of UTe$_2$ coincides with that of UB$_2$, which is an itinerant compound with a nearly $5f^3$ configuration. However, the main peak of UTe$_2$ is broader than that of UB$_2$, 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 UTe$_2$ is in a mixed valence state with a dominant contribution from the itinerant $5f^3$ configuration.
