Crystal field splitting of Pr3+ in PrAl2 investigated by inelastic neutron scattering

Abstract We report the.results of an experimental determination of the crystal field splitting of Pr 3+ in PrAl 2 by means of inelastic neutron scattering. For the crystal field parameters we obtain B 4 = (47.2 ± 4.0) × 10 −4 meV and B 6 = − (156 ± 12) × 10 −6 meV.
