Abstract: | The initial slopes of the acoustic phonon dispersion curves in (V0.98Cr0.02)2O3 have been measured at room temperature in several of the high symmetry directions by inelastic neutron scattering. From these data several sound velocities and four independent elastic constants have been determined. Although the Cr doped specimen is in the insulating phase and pure V2O3 is metallic, these results are in good agreement with recent data (1) obtained by ultrasonic measurements on pure V2O3. |
