It is found that in the low magnetic field H≤9 kOe the magnetization data obey the 3D XY scaling, while the 3D Ginzburg-Landau/lowest Landau level scaling becomes more dominant for H>9 kOe. This observation, which is also supported by the glass-like fluctuation analysis of the in-plane magneto-transport data, implies a suppression of the 2D fluctuation effect which has so far been reported for the Bi-2212 sample. This new characteristics is argued to be the consequence of interlayer coupling enhancement due to excessive oxygen content as manifested by the corresponding strengthening of c-axis coherent length. © 2001 Elsevier Science B.V.
