摘要：

The results of a study of anisotropy in the transport critical current (J(c)), at 77K, under a magnetic field for textured Ag-(Bi,Pb)2Sr2Ca2Cu3Ox tapes as a function of two separate angular rotation sequences, are presented. The measurements show that for a given magnetic field both of the angular rotation sequences give identical values for I(c)(mu(o)H) versus the angle of rotation and the above function can be fitted by the \cos(phi,psi)\-alpha, where the scaling parameter alpha is a function of the magnetic field and the microstructure of the tapes. The influence of the relaxation of the trapped magnetic flux on I(c) parallel-to H and I(c) perpendicular-to H is presented.
