Abstract

We present ultrasonic measurements on the rare earth tritelluride HoTe3 compound. Different anomalies are observed at the upper and lower charge density wave phase transition T[Formula: see text] = 284 K and T[Formula: see text] = 120 K. A striking T2 temperature dependence of the velocities of the longitudinal C[Formula: see text], C[Formula: see text] and shear C[Formula: see text] modes is observed in the ordered phase below the lower CDW phase transition T[Formula: see text]. Such a behavior is related to the temperature dependence of the CDW order parameter.
