摘要：

The Ag/Bi-Sr-Ca-Cu-0 (BSCCO) interface in Ag-clad Bi-2212 tapes was investigated by high-resolution transmission electron microscopy. The interface was found to be well bonded and free of nonsuperconducting second phases. However, a one-half-unit-cell-thick layer of the Bi-2201 phase was observed between the Bi-2212 phase and the Ag-cladding. A very strong texturing of the (001) planes of the BSCCO parallel to the Ag was seen. When the interface was nearly parallel to the Bi-2212 (001) planes, it tended to facet onto (001), leaving steps of height equal to one-half the Bi-2201 lattice spacing. Thus, strong (001 ) texturing extends to the atomic scale.
