| The ab initio self-consistent calculations were performed for USn 2 compound, which crystallizes in the ZrGa 2 -type structure (Cmmm space group). The tight binding linear muffin-tin orbital method in the atomic sphere approximation was used in the calculations. The spin-polarized calculations confirmed the antiferromagnetic order in the USn 2 system. The magnetic moment is predominantly located on the uranium atoms and is formed mainly by the f electrons. The three types of Sn atoms may be treated as non-magnetic. |
