dc.description.abstractWe present inelastic neutron scattering measurements on the heavy-fermion compound Ce(Ru1−xFex)2Ge2Ce(Ru1−xFex)2Ge2 (x = 0.87)(x=0.87). This composition is close to the quantum critical point (QCP) compound (x = 0.76)(x=0.76) in which it was observed that the decay of spin fluctuations could no longer be described by a simple exponential in time. Here we show that the relaxation mechanism for spin fluctuations exhibits a qualitatively similar momentum and temperature dependence in both compositions, possibly reflecting the underlying scaling law at the QCP. However, the details of the relaxation mechanism demonstrate that critical fluctuations are strongly damped along the composition axis.en_US
