Abstract

Polarised-neutron experiments have been performed on a single crystal of paramagnetic URuAl with the ZrNiAl hexagonal structure. Comparisons with the magnetisation density previously determined for ferromagnetic URhAl show that in both materials there is a large magnetic moment induced by hybridisation between the 5f and 4d electrons at the 4d site. This is approximately 30 % of the strength of the uranium signal. However, these effects are present only on the d sites in the (001) plane - an equally close d site out of the plane shows no such effects. These results highlight the importance of anisotropic 5f-ligand interactions.
