摘要

The article presents the first observation of nano-range periodic self-oscillations of atomic displacements in Nd_2Fe_(14)B crystals irradiated by yrays with energy up to 6 MeV. The oscillation period takes 15-20 days in the course of 60 days after the end of irradiation. The phenomenon was discussed in terms of the creation of vacancies and their motion. The calculated vibration spectrum was analyzed to consider possible mechanisms of the motion of vacancies.
