Abstract

We used inelastic neutron scattering to study magnetic excitations of Sc1-xUxPd3 for U concentrations (x = 0.25, 0.35) near the spin glass quantum critical point (QCP). The excitations are spatially incoherent, broad in energy (E = hω), and follow ω/T scaling at all wave vectors investigated. Since similar ω/T scaling has been observed for UCu5-xPdx and CeCu6-xAu x near the antiferromagnetic QCP, we argue that the observed non-Fermi-liquid behavior in these f-electron materials arises from the critical phenomena near a T = 0 K phase transition, irrespective of the nature of the transition.
