Abstract

We have measured the dependence of the CDW elastic depinning anomalies on frequency and uniaxial strain. The anomalies in shear and Young's moduli are approximately independent of frequency between 30Hz and 1kHz, falling rapidly above this. The shear modulus anomaly decreases rapidly when the strain exceeds ∼0.5%, where a second threshold electric field is observed.
