Low-energy nuclear spin excitations in NdAl2
Low-energy nuclear spin excitations in NdAl2
We investigated the low energy excitations in NdAl2 in the mu eV range by a backscattering neutron spectrometer. The energy scans on a NdAl2 single crystal revealed inelastic peaks at E=3.3 +/- 0.1 mu eV at T=3 K on both energy gain and energy loss sides. The inelastic peaks move gradually toward lo...

We investigated the low energy excitations in NdAl2 in the mu eV range by a backscattering neutron spectrometer. The energy scans on a NdAl2 single crystal revealed inelastic peaks at E=3.3 +/- 0.1 mu eV at T=3 K on both energy gain and energy loss sides. The inelastic peaks move gradually toward lower energy with increasing temperature and finally merge with the elastic peak at the electronic magnetic ordering temperature T-N approximate to 79 K. We interpret the inelastic peaks to be due to the transition between hyperfine-split nuclear level of the Nd-143 and Nd-145 isotopes with spin I=7/2. |
