N2 - Magnetic flux relaxation over the surface barrier in high temperature superconductors are investigated. Vortex dynamics controlled by the penetration both of pancake vortices and vortex lines are discussed. The penetration field H p for pancakes decays exponentially with temperature. The size of the magnetization loop is determined by the decay of H p during the process of relaxation, but its shape remains unchanged. The irreversibility line associated with the pancake penetration is given by H irr ∞ exp(−2 T / T c ), and may lie both above and below the melting line.
