Abstract

We are investigating the delocalization of 5f{hook} electrons in uranium compounds by means of the de Haas-van Alphen(dHvA) experiment. The measurements of moderately-heavy fermion compound U₃P₄ show the complicated angular dependence of the cross-sectional area of the Fermi surface. By contrast, the angular dependence in U₃As₄ seems rather simple, corresponding to the smaller electronic specific heat coefficient. This result seems to be due to weaker hybridization of 5f{hook} electrons with ligands in U₃As₄ than in U₃P₄.
