Descripción
Memory effects (ME) in the solid vortex lattice (VL) are observed in a wide range of superconducting materials. Experiments in twinned
Y Ba2Cu3O7 (YBCO) crystals in a DC magnetic field tilted respect to the twin planes indicate that ME in these samples cannot be
ascribed to an equilibration process. However, how extensive is this behaviour, has not been explored so far. In this work we study
the role of correlated defects in ME by performing angular ac susceptibility measurements in YBCO crystals. We conclude that, when
uncorrelated disorder prevails, either in twinned or untwinned samples, ME have their origin in the oscillatory character of the vortex
dynamics.
