Search for soft phonon modes in Zr2Ni

摘要

Inelastic neutron‐scattering measurements have been made on a zgr;00 transverse acoustic phonon branch of Zr2Ni at several temperatures between 300 and 10 K. The experiment was motivated by previous ultrasonic results which showed a large softening of the related elastic constantC66. No phonon softening was observed in our experiment, but a fairly unusual dispersion was noted.
