Electronic structure and magnetism of UxTh1-xSb as studied by photoemission

Abstract

Using photoelectron spectroscopy with synchrotron radiation in the 10<~h <~130 eV range, we have studied the "5f,6d" electron states in single crystal UxTh1-xSb. We find that uranium has a quasilocalized 5f resonant level with essentially a trivalent configuration and does not change valence in the ordered magnetic region 1.0>~x>~0.3 while thorium contributes 6d conduction-band electrons which play an important role in both the electronic and magnetic properties. © 1981 The American Physical Society.
