| Abstract: | Measurements of light scattering from acoustic spin waves in CrBr3 in both the ferromagnetic and paramagnetic states are reported. The dispersion is shown to be adequately described in terms of a single anisotropy constant. Lifetime measurements are compared to those obtained by ferromagnetic resonance techniques. Anomalous effects arising from the very high magnetooptic coupling are discussed. |
