摘要：
We report measurements of the conductivity transition of a Bi2Sr2CaCu2O8 (Bi-2212) single crystal. Several magnetic fields up to 200 Oe were applied either parallel or perpendicular to the measuring current. We derive H-T phase diagrams showing the regions of dominance of 3D-XY, Gaussian and LLL fluctuation regimes above the critical temperature.
