Abstract
Measurements of the magnetoresistance R(H) as functions of the temperature and the angle θ between the applied magnetic field and the plane of a (Bi,Pb)2Sr2Ca2Cu3O/Ag tape have been performed in a low magnetic field region below Tc. Contrary to the two-dimensional vortex pancake model, the data do not scale well with H sin(θ) for small angles. Instead, our results show a general three-dimensional scaling behavior based on the anisotropy in the upper critical field Hc2 over entire angular range. From the scaling, the dissipation anisotropy is found to be unchanged at lower temperatures and decreases with increasing temperature at temperatures close to Tc.
