“…6 If the anisotropy were driven by hybridization-mediated f -f coupling only, one would anticipate a moment configuration perpendicular to the shortest U-U distance in all cases ͑similar to the findings in UTX compounds͒. While this was found to be true in U 2 Pd 2 X compounds, 23 the case of U 2 Ni 2 Sn seems to contradict this rule. 24 As an aside, we note that very recent bandstructure calculations including spin-orbit coupling have reproduced the experimentally observed noncollinear antiferromagnetic structure in U 2 Pd 2 Sn, and it was shown that this structure is energetically preferred over the other possible moment arrangements.…”

Hybridization effects in U2T2X compounds: Magnetic structures of U2Rh 2Sn and U2Ni 2In Nakotte, H.; Purwanto, A.; Robinson, R.A.; Prokes, K.; Klaasse, J.C.P.; de Chatel, P.F.; de Boer, F.R.; Havela, L.; Sechovsky, V.; Pereira, L.C.J.; Seret, A.; Rebizant, J.; Spirlet, J.C.; Trouw, F.

The tetragonal intermetallic compounds U 2 Ni 2 In and U 2 Rh 2 Sn have been studied by means of specific-heat, electrical-resistivity, and neutron-diffraction techniques. At low temperatures, both compounds order antiferromagnetically in a magnetic unit cell doubled along the c axis, and we find 5 f moments of 0.60 and 0.38 B /U atom for U 2 Ni 2 In and U 2 Rh 2 Sn, respectively. For U 2 Ni 2 In, our refinement also indicates a possible Ni moment of 0.37 B perpendicular to the U moments. We discuss the development of the 5 f moments together with findings on other isostructural U 2 T 2 X ͑Tϭtransition metal, XϭIn, Sn͒ compounds, and confirm that the trends expected due to 5 f -ligand hybridization also hold for this family of uranium compounds. Our analysis indicates different arrangements of the 5 f moments in the two compounds ͑noncollinear arrangement within the basal plane for U 2 Ni 2 In and collinear arrangement along the c axis for U 2 Rh 2 Sn͒, although both compounds have nearest-neighbor U-U distances along the c axis. This would mean that the magnetocrystalline anisotropy in U 2 T 2 X compounds is not determined by nearest-neighbor U-U links alone.

Download date: 10 May 2018Journal of Magnetism and Magnetic Materials 140-144 (1995) AbstractMagnetic and other electronic properties are presented for the U2T2X compounds (T = late transition metal, X = Sn or In), that crystallize in the tetragonal U3Si2-type structure. They show the formation of 5f magnetic moments and antiferromagnetic ordering in compounds where weak 5f-d hybridization is expected. Near the onset of magnetic ordering strongly enhanced y-values are found. Neutron-diffraction experiments on U2Pd2Sn and U2Pd2In point to a connection between the mutual coordination of U atoms and the type of magnetic anisotropy.
