Abstract
By exposure of YBa2Cu3O7 to hydrogen at moderate temperatures, the sup
erconductivity properties, T-c and Meissner volume fraction, are, depe
nding on the treatment conditions, differently affected. Although no m
ajor changes are detected by X-ray diffraction, the microstructure of
the obtained products is quite complex, and a significant amount of di
sorder is produced. The results are also compared with those produced
in the reduction performed with n-butyllithium.
