Abstract

We performed inelastic neutron scattering experiments on polycrystalline samples of the heavy fermion compounds Ce ₂ X (X = Sb, Bi). We observed a well-defined magnetic peak at 5.4 ± 0.1 meV in an inelastic spectrum of Ce ₂ Bi at 21 K, which indicates that Ce ₂ Bi includes well localised 4f states. In contrast, Ce ₂ Sb shows only broad magnetic scattering with a small magnetic peak at about 1.5 meV at 21 K.
