Abstract
The angular dependence of the resistivity ρ(θ) has been measured in the superconducting transition region in (Tl2/3,Bi1/3)Sr2CaCu2Ox crystals. This resistivity has been successfully scaled using an anisotropic effective mass model with an anisotropy γ=(mc/mab)1/2 of 9–12, which is larger than in YBa2Cu3O7, but much smaller than in Bi-2212 or Tl-2212 compounds. This study was performed for measurements with the current applied along the ab planes or along the c axis.
