Time evolution of the induction profile across a Bi2Sr 2CaCu2O8+δ crystal was magneto-optically recorded in two experiments: during ramping the external magnetic field or after a sudden application of the field. The results of these experiments reveal a front-like propagation or retreat of a transient disordered vortex state, respectively. Analysis of the front velocity shows that while the retreat is continuously decelerated, the propagation is accelerated, approaching a constant velocity when the front induction reaches the vortex order-disorder phase transition field Bod. The latter observation suggests a method for determining the value of Bod, eliminating transient state effects.
