Résumé

The set of elastic constants of the charge density wave (CDW) rare earth tritelluride TbTe3 has been measured at 15 MHz in the temperature range 300-360 K. Large anomalies in the velocity and ultrasonic attenuation of the longitudinal C11 and C33 modes are observed at the charge density wave phase transition TCDW = 333 K. Anisotropic stress dependence dTCDW/dp is found, the component dTCDW/dp1 and dTCDW/dp3 in the (a,c) plane are one order of magnitude larger than the component dTCDW/dp2 perpendicular to it. The Landau theory has been used to explain the explain the experimental data.Critical behavior near the charge density wave phase transition is described in terms of a phenomenological dynamic scaling theory.
