Abstract

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 Γ₄ singlet and the first excited level is a Γ₅⁽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.
