Unusual 5f magnetism in the U2Fe3Ge ternary Laves phase: a single crystal study

Original language description

Magnetic properties of the intermetallic compound U2Fe3Ge were studied on a single crystal. The compound crystallizes in the hexagonal Mg2Cu3Si structure, an ordered variant of the MgZn2 Laves structure (C14). U2Fe3Ge displays ferromagnetic order below the Curie temperature TC = 55 K and presents an exception to the Hill rule, as the nearest inter-uranium distances do not exceed 3.2 ?. Magnetic moments lie in the basal plane of the hexagonal lattice, with the spontaneous magnetic moment Ms = 1.0 ?B/f.u.at T = 2 K. No anisotropy within the basal plane is detected. In contrast to typical U-based intermetallics, U2Fe3Ge exhibits very low magnetic anisotropy, whose field does not exceed 10 T. The dominance of U in the magnetism of U2Fe3Ge is suggested bythe 57Fe Mössbauer spectroscopy study, which indicates very low or even zero Fe moments. Electronic structure calculations are in agreement with the observed easy-plane anisotropy but fail to explain the lack of an Fe contribution to the
