Abstract
We have measured anelastic properties of (TaSe4)(2)I by applying a dir ect current in a 5 Hz torsion experiment. We obtained an anelastic mod ulus decrease of as much as 30% and a maximum internal friction increa se of 1500%. From frequency analysis of the anelastic properties betwe en 5 Hz and 10(-3)Hz we have obtained relaxation times which run betwe en 0.1 and 2 s. These results confirm previous works indicating the re laxation character of the changes observed in the anelastic properties , but keep open the question of the relaxing entity.
