| Description | Journal: Journal of Physics: Condensed Matter A polarized neutron scattering experiment and an x-ray magnetic circular dichroism (XMCD) study at the $M_{4,5}$ edges of uranium have been performed on a single crystal of the heavy-fermion superconductor $UNi_{2}Al_{3}$ in the paramagnetic phase. Projections of the maximum-entropy reconstructions of the magnetization distribution obtained from neutron data evidence a large and almost spherical distribution on the U sites and an induced moment at the Ni sites. Refinements of the magnetic structure factors within the dipolar approximation allow one to quantify the Ni contribution and the orbital and spin uranium moments, and reveal a diffuse contribution parallel to the 5f moment. The XMCD study leads to a value of the 5f orbital contribution in agreement with the neutron one. For both neutron and XMCD experiments, we compare our results with previous measurements performed on the parent compound $UPd_{2}Al_{3}$. |
