URhAl is a ferromagnet (T(C)=27 K) with a moment of 1 u(B) per mole directed parallel to the unique hexagonal axis of the structure. The material is known to exhibit an enormous anisotropy, which is thought, in part, to arise from the hybridization of the U 5f with the Rh 4d electrons. In this paper measurements have been performed on a large polycrystalline sample at the high energy transfer (HET) spectrometer at the ISIS spallation source (GB) to characterize the magnetic response function as a function of energy. Evidence for the interaction with the conduction electrons and for the spin gap is presented.
