Elastic properties of FeSi

Measurements of the sound velocities in a single crystal of FeSi were performed in the temperature range 4–300 K. Elastic constants C 11 and C 44 deviate from a quasiharmonic behavior at high temperature; on the other hand, elastic constants C 12 increases anomalously in the entire temperature range...

Description
Summary:Measurements of the sound velocities in a single crystal of FeSi were performed in the temperature range 4–300 K. Elastic constants C 11 and C 44 deviate from a quasiharmonic behavior at high temperature; on the other hand, elastic constants C 12 increases anomalously in the entire temperature range, indicating a change in the electron structure of this material.
