Abstract
We present an analysis of the measured excess conductivity which results from the fluctuation of the superconducting order parameter of a Bi2Sr2CaCu2O8+y single crystal and found it was fit best by the two-dimensional Aslamazov-Larkin theory. The magnetoconductivity and magnetization studies are in good agreement with the two-dimensional (2D) scaling behavior in the fremework of Lawrence-Doniach model revealing the 2D nature of the fluctuation near the mean-field transition temperature in the presence of a field.
