Abstract

We report on measurements of the angular dependence of the irreversibility temperature T_irr(θ) in YBa₂Cu₃O_7-δ films. We find that neither depinning nor melting are responsible for the appearance of magnetic reversibility. Instead, we find evidences that T_irr is determined by a crossover from pinned to unpinned vortex liquid.
