Thermal annealing of the torn vortex lattice in YBa 2Cu 3O 7 crystals

We report evidence that the ac driven solid vortex lattice in YBCO single crystals reorganizes and accesses to robust configurations with different effective pinning potential wells arising in response to different system histories. The curvature of the pinning wells was determined by measuring the...
