“…6 A chemical analysis re-vealed that their composition is very close to the stoichiometric one. This was confirmed by measurements of T c and the tetragonal transformation temperature T M (T c = 18.0 ±0.1 K, T M = 35-50 K).…”

Phonon Anomalies inNb3Sn

1985

Small single crystals of Nb 3 Sn were grown and used to study the lattice dynamics by means of inelastic neutron scattering. Almost complete sets of phonon dispersion curves could be obtained for the main symmetry directions. The results are generally in very good agreement with the predictions of Weber based on the nonorthogonal-tight-binding method. In particular it has been confirmed that the (111) LA branch exhibits a pronounced anomaly.
