Electronic structure of the uranium monogermanide UGe

Abstract The uranium monogermanide (UGe) crystallizes in the orthorhombic ThIn-type structure (Pbcm space group) in which the uranium and germanium atoms each occupy three crystallographic positions. The electronic structure of UGe compound has been studied using spin-polarized tight binding version of the linear muffin-tin orbital method in the atomic sphere approximation (TB LMTO ASA). The calculations showed that all three types of uranium atoms are magnetically ordered and their spin magnetic moments are equal to: −2.02,+1.88, and −0.24 μ B /atom.
