摘要：

We have determined the inelastic magnetic response S(omega) of UPdxCu(5-x) (x = 1, 1.5) for temperatures from 0.3 K to 300 K and energies between 0.5 meV and 100 meV using the neutron time of flight technique. S(omega) is virtually identical in the two compounds, displaying marginal Fermi liquid scaling over the entire range of temperatures, as well as scale invariant energetics.
