Shortly after the announcement of the discovery of
superconductivity in the MBi-GIC's, an effort was undertaken at MIT to
reproduce the results reported by the University of Nancy group. As
described in Section , the samples used in the MIT
experiments were prepared using conditions close to those used in Nancy.
The x-ray diffraction patterns, TEM micrographs, and sample colors were
found to be similar to those previously reported [see
Chapter
].
