Description
In order to understand the origin of the spin glass ground state in the stoichiometric compound PrAu2Si2, we have performed inelastic neutron scattering measurements of the crystal field (CF) excitation spectrum. The 4f ground state is a Γ 4 singlet and the first excited level is a Γ 5(2) doublet at 0.72 meV. We compare the CF potential with other isostructural compounds to determine what features of the CF splittings are essential in producing spin glass freezing in a structurally ordered compound
