Temperature Dependent 5f-states in URu_2Si_2
arXiv:cond-mat/0107357 · doi:10.1016/S0921-4526(01)01290-X
Abstract
A dramatic temperature dependent enhancement of U 5f spectral weight at $E_F$ is observed in angle-resolved photoemission measurements of $URu_2Si_2$ at the center of an X-point hole-pocket. Comparison of this temperature dependent behavior for excitation both at and below the U $5d \to 5f$ resonant threshold is presented.
