AbstractNeutron scattering results for the tetragonal compound (formula presented) give evidence for two crystal field (CF) excitations at 6.9 and 23.6 meV. The scattering can be fit assuming a set of CF parameters (formula presented) (formula presented) and (formula presented) To compare our results with previous work, we calculate the susceptibility and specific heat for this CF scheme, including a molecular field term (formula presented) to account for the Kondo effect. We also include a calculation based on these CF parameters, which uses the noncrossing approximation to the Anderson model to estimate the effect of Kondo physics on the susceptibility, specific heat, and neutron linewidths. © 2002 The American Physical Society.
