The electric field gradient (EPPES) at Hf sites in amorphous Hf& Cu"alloys was measured for x =0. 33, 0.44, 0.50, and 0.59 with use of the time-differentia1 perturbed angular correlation technique. The results show no evidence of crystallinelike local order in these alloys, supporting a description of their local structure in terms of a dense random packing of atoms. The local and lattice contributions to the EFCx, as well as their dependence on composition, are discussed.
