Electronic and Spin Structure of UTe

Abstract

A self-consistent cellular multiple-scattering technique is used to calculate the density of states of uranium telluride. The $5f$ band is found to be highly polarized and energetically localized although presenting enough itinerant character to keep its position at the Fermi level. The material shows a coupling between the $5f$ and $6d$ states. This interaction explains the observed negative spin polarization from photoelectrons up to 7 eV above the photothreshold.
