Abstract

We report a pronounced critical current anisotropy in bar shaped samples formed from different particle sizes as a function of the magnetic field orientation. Anisotropy of the critical current in tape form wires confirms the measurements on bar samples. X-ray measurements indicate a c-axis preference parallel to the compression axis.
