摘要：
The mechanisms giving rise to the irreversibility line (IL) in the phase diagram of Bi2Sr2CaCu2O8 and the mechanism behind the second maximum in the magnetization loops were determined using a novel Hall-sensor array. The IL is caused by bulk pinning at lower temperatures and by irreversible shielding currents above 22K. The second maximum is caused by vortex lattice melting, taking place at the same local magnetic induction B-m throughout the sample.
