Abstract
Making use of the Hamiltonian for linear magneto-elastic coupling which has been proposed by Callen and Callen, expressions are deduced for changes in the velocity of acoustic waves in a terbium crystal, due to ferromagnetic ordering and the application of an external magnetic field. These calculations agree semi-quantitatively with the results of experimental measurements.
The author has examined the extent to which this simple picture is applicable to explain the magnon-phonon interactions in terbium, which have been observed at finite wave vectors by inelastic neutron scattering
