Magnetization Decay due to Vortex Phase Boundary Motion in BSCCO
arXiv:cond-mat/9912283 · doi:10.1016/S0921-4534(00)00918-7
Abstract
We identify a new regime of decay of the irreversible magnetization in clean Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8}$ crystals, at induction values close to the ``second peak field'' at which the bulk critical current density steeply increases. A time window is identified during which the decay of the induction is controlled by the slow propagation of the phase transformation front across the sample.
