Measurements of the magnetoresistanceR(H)as functions of the temperature and the angle &thgr; between the applied magnetic field and the plane of a(Bi,Pb)2Sr2Ca2Cu3O/Agtape have been performed in a low magnetic field region belowTc.Contrary to the two-dimensional vortex pancake model, the data do not scale well withH sin(&thgr;)for small angles. Instead, our results show a general three-dimensional scaling behavior based on the anisotropy in the upper critical fieldHc2over 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 toTc.©1998 American Institute of Physics.
