Abstract

For the hexagonal ferromagnet UNi(2), an unusual 5f form factor for uranium has been observed, indicating a large orbital contribution to the total moment. Self-consistent electronic structure calculations for the hexagonal Laves phase (C14) compound UNi(2) are described, taking both spin and orbital contributions to the total moment into account. In a constrained calculation, where the spin moment is chosen to agree with experiment, very good agreement with the experimental form factor is obtained. In the analysis of the form factor both the 6d and the 5f electrons are taken into account, giving improved agreement with experiment.
