Memory effects in the dynamics of the vortex lattice in YBCO crystals: The role of correlated disorder

Memory effects (ME) in the solid vortex lattice (VL) are observed in a wide range of superconducting materials. Experiments in twinned Y Ba 2Cu3O7 (YBCO) crystals in a DC magnetic field, tilted with respect to the twin planes, indicate that ME in these samples cannot be ascribed to an equilibration...
