Mw. Lee et al., INFLUENCE OF HYDROGEN ABSORPTION ON MAGNETIZATION IN SUPERCONDUCTING YBA2CU3O7-DELTA POWDERS, Physica. C, Superconductivity, 235, 1994, pp. 851-852
Hydrogen (H) absorption by YBa2Cu3O7-delta (YBCO) was carried out by e
xposing the superconducting powders to rf-generated H plasma. We find
that both the field-cooled (FC) and zero-field-cooled (ZFC) susceptibi
lities increase after hydrogenation. The largest enhancement is about
24% for the FC susceptibility at 5K.
