Abstract

Inelastic neutron scattering experiments on a single crystal of PrNi5 (0.4 cm3) were performed at the sample temperature T = 8 K. The dispersion relations of the acoustic transverse phonons and the low-energy magnetic excitations were measured in the T and Δ-directions. An analysis of the intersection region of these excitations shows that an additional neutron intensity to the nuclear and magnetic dipolar scattering occurs due to magnetoelastic scattering. The hybridized spectra of phonons and quadrupole excitons are discussed.
