Abstract

We have extended Bean's critical state model to explicitly include anisotropic critical currents. Measurements at 30 K of the critical currents parallel to the Cu-O planes but with vortex motion either parallel or across twin boundaries show twin boundaries are probably not an important cause of vortex pinning. In the critical state, current flow perpendicular to the Cu-O planes is about 30 times smaller than flow parallel to these planes.
