摘要：

The anomalous magnetic phase transition in UNiSn is explained on the basis of electronic-structure calculations. The energy band approach in which the local density Hamiltonian is generalized with an additional on-site Coulomb interaction U provides a fully satisfactory picture of both the metallic antiferromagnetic ground state and the paramagnetic semiconducting state, with a band gap of 0.12 eV, as well as a total energy difference of the correct magnitude as compared to the Neel temperature.
