Low-energy phonons in magnetite
Description
Abstract Acoustic and some optic phonon branches have been observed by means of inelastic neutron scattering in magnetite at room temperature and near the Verwey transition at T v = 119 K. No appreciable effect on the phonon spectrum was found in passing T v . Sound velocities determined at room temperature were found to agree only moderately with ultrasonic data, and they show marked deviation from cubic symmetry, which possibly could be interpreted in terms of anharmonic effects.
