Anelastic behavior was studied in hydrogenated samples. Two complex peaks were detected at temperatures ranging from 80 to 500K. The low-temperature peak, at 100 to 270K, was recognized as being a H-induced Snoek-like relaxation peak, while the high-temperature peak was attributed to a transient process. The low-temperature peak was attributed to the movement of H atoms between the energetically equivalent octahedral sites. This defined the fine structure of the peak. A non-monotonic dependence of the peak height upon the charging current density suggested the possible involvement of hydride phases.
