Low-energy nuclear spin excitations in CoO
Low-energy nuclear spin excitations in CoO
We investigated the low-energy excitations in CoO in the mu eV range by a back-scattering-neutron spectrometer. The energy scans on a CoO single crystal revealed inelastic peaks at E=2.05 +/- 0.02 mu eV at T=3.5 K on both energy-gain and energy-loss sides. The inelastic peaks move gradually toward l...

We investigated the low-energy excitations in CoO in the mu eV range by a back-scattering-neutron spectrometer. The energy scans on a CoO single crystal revealed inelastic peaks at E=2.05 +/- 0.02 mu eV at T=3.5 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 290 K. We interpret the inelastic peaks to be due to the transition between hyperfine-split nuclear level of the Co-59 isotopes with spin I=7/2. |
