Query: Low energy spin fluctuations in the heavy fermion compound
  Ce$_{0.925}$La$_{0.075}$Ru$_{2}$Si$_{2}$   We report inelastic neutron scattering measurements performed on a single
crystal of the heavy fermion compound Ce$_{0.925}$La$_{0.075}$Ru$_{2}$Si$_{2}$,
which is at the borderline between an antiferromagnetically ordered and a
paramagnetic ground state. Intensity maps as a function of wavevector and
energy ($0.1<E<1.2$ meV) were obtained at temperatures $T=0.1$ and 2 K, using
the time-of-flight spectrometer IRIS. An unexpected saturation of the
relaxation rate and static susceptibility of the spin fluctuations is found at
low temperatures.
