摘要：

Crystal structure and magnetic susceptibility behaviour of UOSe single crystals have been studied. UOSe crystallizes in the tetragonal PbFCl-type structure (space group P4/nmm) with the lattice parameters: a = 390.38(5) pm and c = 698.05(9) pm. It orders antiferromagnetically at T(N) = 100 +/- 2 K and exhibits a very strong anisotropy in the susceptibility vs temperature variation. The magnetic and thermodynamic properties of UOSe are successfully interpreted in the framework of a perturbative ab initio crystal field approach.
