摘要：

We use a combination of relaxation measurements and magnetic hysteresis loops at different field ramp rates to explore the dynamical behavior of the second peak in the magnetization of Bi2Sr2CaCu2O8 crystals. We find that the second peak is absent in the short-time limit. It evolves at intermediate time scales due to a different decay rate of the Bean profile at fields above and below the second peak. At long time scales, when the Bean profile for fields below the second peak has decayed, the size of the second peak saturates. Finally, while the Bean profile above the second peak field slowly decays, the second peak decreases and vanishes.
