Summary

The authors' experiments on clean, detwinned YBCO crystals at temperatures around 80-90 K reveal an interplay between surface pinning and weak bulk pinning that leads to the formation of a defect superstructure in the vortex lattice. This current-induced organization is similar to phenomena observed in the dynamics of sliding charge-density waves, and represents a fundamentally new kind of vortex dynamics.
