ELASTIC PROPERTIES OF FeSi
Petrova A.E., Krasnorussky V.N., Stishov S.M.
Поступила в редакцию: 11 Марта 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.
