Abstract

Neutron scattering results for the tetragonal compound CeRhIn₅ 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 B₂⁰= -1.03 meV, B₄⁰=0.044 meV, and B₄⁴=0.122 meV. To compare our results with previous work, we calculate the susceptibility and specific heat for this CF scheme, including a molecular field term λ = 35 mol/emu 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.
