OSTI ID:6607467
The magnetization in single phase YBa/sub 2/Cu/sub 3/O/sub 7/ shows a 5 : 1 ratio between flux exclusion (diamagnetic shielding) and flux expulsion (Meissner effect). These results plus other complementary data suggest that the superconductivity is confined to thin shells surrounding normal metallic grains.
