Temperature dependent 5f-states in URu2Si2
/ Authors
/ Abstract
A dramatic temperature dependent enhancement of U 5f spectral weight at EF is observed in angle-resolved photoemission measurements of URu{sub 2}Si{sub 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->5f resonant threshold is presented.
