✦ Synopsis

We have examined the spin dynamics of U0 2Yo.sPd3 and U0.45Yo 55Pd3, at low temperatures, using inelastic neutron scattering techniques. In U0.45Yo.55Pd 3 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.zY08Pd 3 is much weaker, and the excitations are strongly damped with a Lorentzian (relaxational) response.
