Abstract

We have measured the angle dependence of magneto-resistivity for pure Bi₂Sr₂CaCu₂O_8+δ single crystals with various oxygen contents. Blatter's scaling rule was applied to estimate the anisotropy γ in the superconducting state. With reducing oxygen content, obtained γ increases in proportional to the square root of the ρ_c at just above T_c. These results can be quantitatively explained by the Lawrence-Doniach model. However, the obtained γ has a temperature dependence, which suggests anomalous effect on the interlayer coupling η near T_c.
