Dynamics of the magnetization in the heavy fermion system CeCu6

We have studied CeCu6 by inelastic neutron scattering. We found both quasielastic and also inelastic transitions, which we interpret as residual crystal field transitions. The quasielastic linewidth is a strongly nonlinear function of temperature, with approximately ΓQE=5.0 meV at 300 K, with a crossover ΓQE=kT at about 13 K and with a residual value of ΓQE=(0)=0.50 meV for T=0 K. Below 5 K the quasielastic intensity IQE decreases linearly with temperature. χstαIQE/T is in good agreement with direct measurements of the static susceptibility. The data are fully consistent with a nonordering groundstate of CeCu6. © 1986 Springer-Verlag.
