Resumen:
We have performed magnetization measurements onBi$_2$Sr$_2$CaCu$_2$O$_{8-\delta}$ single crystals in the {\bf c}crystallographic direction for fields from 2 Oe up to 700 Oe. The resultsstrongly suggest that the reversible thermodynamic region is achieved after the vortex flux structure shows anabrupt transition at a temperature lower than that determined by the irreversibility line.
