摘要：

The magnetic excitations in single crystal UPd3 have been studied by inelastic neutron scattering. At 1.8 K, we find at a general wave vector, four modes below 3 meV which we ascribe to crystal field-like excitations on the quasi-cubic sites. Their temperature dependence has been measured and the results are explained in terms of a quadrupolar transition at T1 = 6.5 K, followed by a magnetic transition at T2 = 4.5 K.
