Abstract
We report a study of the resistive transitions in Bi2Sr2CaCu2O8+x in presen ce of an applied magnetic field (up to 12 tesla) at various field orientati ons. We focus our attention on the results obtained with orientations paral lel and perpendicular to the (a,b) planes. We show that scaling arguments, typical of dissipative regimes independent of oriented defects, can explain the experimental findings, provided a 3D-2D crossover is assumed as the te mperature is lowered, due to the variation of the out of plane coherence le ngth.
