Abstract

A high-temporal resolution magneto-optical system was employed to follow the time evolution of the second magnetization peak in Bi2Sr2CaCu2O8+δ. Local magnetization curves at different times, demonstrated the absence of the second magnetization peak at short times, its appearance at longer times and the movement of its onset toward higher-induction fields approaching the therodynamic vortex order-disorder transition field. It was shown that the time evolution of the second magnetization peak is governed by the relaxation times of the metastable vortex states.
