This topical review presents results from neutron inelastic scattering experiments on single crystals of UPdAl. We present a detailed and complete characterization of the wave vector- and energy-dependent magnetization dynamics in UPdAl as measured by neutron inelastic scattering primarily in the form of extensive surveys in energy-momentum space under a wide range of experimental conditions, and put our observations in context with data that has been published previously by two independent groups. This study yields unique insight into the low-temperature ground state, which exhibits a microscopic coexistence of antiferromagnetism and superconductivity, makingUPdAl one of the most accessible heavy-fermion superconductors that can be fully characterized by neutron spectroscopy.
