Abstract

Local magnetization curves at different times, extracted from high-temporal resolution magneto-optical measurements in Bi₂Sr₂CaCu₂O_8+δ, demonstrate the absence of the second magnetization peak (SMP) at short times, its appearance at longer times, and the movement of its onset toward higher induction fields approaching the limit of the thermodynamic order-disorder transition field. We utilize theoretical analysis, based on the Landau-Khalatnikov dynamic equation adopted for the vortex matter order parameter, to simulate the measured time evolution of the SMP. We show that the observed time evolution is a manifestation of a dynamic coexistence of transient-disordered and ordered vortex phases.
