Abstract

Calculations for NaCl-type uranium compounds are able to explain trends in lattice constant and bulk modulus, the onset of magnetic ordering and the observed relationship between lattice constant and magnetic moment. Relativistic effects alter the calculated magnetic properties dramatically being responsible for both large magnetic anisotropy and predominant orbital moments in all magnetic uranium compounds in which the f electrons are itinerant. The calculated magnetic moments of NaCl-type uranium compounds are, however, only in agreement with experiment when the pairing energy between electrons includes an orbital contribution.
