| Abstract: | The elastic constants of the ID-ferromagnet CsNiF3 and their temperature dependence in the 10 K – 300 K range have been obtained using Brillouin scattering and ultrasonic propagation measurements. The results show a marked anisotropy. A small softening of C44 is observed when T decreases : it could arise from magnetic correlations. Comparison with previous experimental data derived from other techniques is discussed. |
