Figure 4
Inelastic absorption spectra from (a) Dy2O3 powder at room temperature and (b) a DyB2C2 crystal at 28 K. Collection times were about 8 and 14 h, and elastic peak heights are 1 × 105 and 4 × 104, respectively. See text for details. Lines are to guide the eye. Insets show the derived partial phonon densities of states (30 meV full scale in each case). |
