Abstract
The recently proposed scaling law relating the diffusion coefficient and th e excess entropy of a liquid [M. Dzugutov, Nature (London) 381, 137 (1996)] is tested for several metals using molecular dynamics simulations. Interat omic potentials derived from the embedded atom method are used to study Ag, Au, Cu, Ni, Pd, Pt, Ni3Al, and AuPt and the angular dependent Stillinger-W eber form is used to investigate Si.
