Extended versus Local Fluctuations in Quantum Critical Ce(Ru1-xFex)2Ge2 (x=xc=0.76) (original) (raw)

2003, Physical Review Letters

We present inelastic neutron scattering experiments, performed near the antiferromagnetic quantum critical point in CeRu 0:24 Fe 0:76 2 Ge 2 . Both local and long-range fluctuations of the local moments are observed, but due to the Kondo effect only the latter are critical. We propose a phenomenological expression which fits the energy E, temperature T, and wave vector q dependences of the dynamic susceptibility, describing the non-Fermi liquid E=T scaling found at every q.
