摘要：

We have examined the spin dynamics of U0 2Y0.8Pd3 and U0.45Y0.55Pd3, at low temperatures, using inelastic neutron scattering techniques. In U0.45Y0.55Pd3 we observe excitations at 2-5 meV and 36 meV, which we attribute to crystal field levels. The energy of the lower branch shows a dispersion characteristic of antiferromagnetic correlations. The magnetic scattering from U0.2Y0.8Pd3 is much weaker, and the excitations are strongly damped with a Lorentzian (relaxational) response.
