Abstract

The inelastic neutron scattering spectra of the CeAl3 heavy-fermion system are measured over a wide range of momentum transfers with the aim of determining the type of ion-ion magnetic correlations. The oscillatory dependence of the intensity of quasi-elastic magnetic neutron scattering on the momentum transfer is revealed at temperatures lower than those corresponding to the energy of splitting in the crystal electric field. An analysis of the obtained dependence of the intensity of quasi-elastic magnetic neutron scattering indicates the presence of short-range ferromagnetic correlations in the system.
