Abstract / Description:We have investigated the low-energy excitations in Nd in the mueV range by a back-scattering neutron spectrometer. The energy scans on Nd revealed inelastic peaks at E = 2.67 +/- 0.06 ReV at T = 60 mK on both energy-gain and energy-loss sides. The inelastic peaks move gradually towards lower energy with increasing temperature, and finally merge with the elastic peak at zero energy transfer at the electronic magnetic ordering temperature T-N approximate to 19.8 K. At about 5 K we observe a second peak at E = 1.8 +/- 0.3 mueV, which also decreases in energy with increasing temperature. This second peak disappears at about 15 K. We interpret the inelastic peaks as low-energy nuclear spin excitations arising due to the Suhl- Nakamura indirect interaction.
