摘要：

We report magneto-optical observations of moving helicoidal vortex structures in high purity YBa2Cu3O7-delta single crystals. We found that the dynamics of these 'vortex-twisters' is mainly controlled by localized instabilities (kinks.) which stream along the helices. The kinks allow the motion of the twisters, or the annihilation of twisters with opposite chirality. (C) 1997 Elsevier Science B.V.
