Received: March 11, 2010
Measurements of the sound velocities in a single crystal of FeSi were performed in the temperature range 4-300 K. Elastic constants C11 and C44 deviate from a quasiharmonic behavior at high temperature; on the other hand, elastic constants C12 increases anomalously in the entire temperature range, indicating a change in the electron structure of this material.
