Abstract
Bulk Bi2Sr2CaCu2O8 + (delta ) (Bi2212) bicrystals containing a single high quality twist grain boundary junction were prepared in order to investigate the orbital symmetry of the superconducting order parameter in highly anisotropic Bi-based high temperature superconductors. The misorientation angles of the bicrystals ranged from 0 degrees to 180 degrees. The microstructure in the vicinity of the junction was characterized using high- resolution, nano-probe analytical microscopy. We fond that some high angle twist junctions were able to carry a critical current density similar to their constituent single crystals. These results cannot be interpreted in terms of a pure dx2-y2-wave order parameter for superconducting Bi2212.
