dc.descriptionThe electronic structures of the localized $5f$ systems UTSn (T=Ni, Pd) have been investigated using photoemission spectroscopy (PES). The extracted U $5f$ PES spectra of UTSn (T=Ni, Pd) exhibit a broad peak centered at $\sim 0.3$ eV below $\rm E_F$ with rather small spectral weight near $\rm E_F$ (N$_f$($\rm E_F$)). The small N$_f$($\rm E_F$) in UTSn is found to be correlated with the T $d$ PES spectra that have a very low density of states (DOS) near $\rm E_F$. The high-resolution PES spectra for UTSn provide the V-shaped reduced metallic DOS near $\rm E_F$ but do not reveal any appreciable changes in their electronic structures across the magnetic phase transitions. A possible origin for the reduced N$_f$($\rm E_F$) in UTSn is ascribed to the hybridization to the very low T $d$ DOS at $\rm E_F$. Comparison of the measured PES spectra to the LSDA+$U$ band structure calculation reveals a reasonably good agreement for UPdSn, but not so for UNiSn.
