摘要：

We have recently reported on the persistence of a significant zero voltage current across bicrystal grain boundary junctions of YBa2Cu3O7-delta in an external magnetic field of several Tesla. In this note we present data on the dependence of this residual current on temperature and orientation of the grain boundary. A description of the grain boundary as being comprised of superconducting microbridges separated by normal regions is consistent with the experimental data.
