Popis: By exposure of YBa2Cu3O7 to hydrogen at moderate temperatures, the superconductivity properties, Tc and Meissner volume fraction, are, depending on the treatment conditions, differently affected. Although no major changes are detected by X-ray diffraction, the microstructure of the obtained products is quite complex, and a significant amount of disorder is produced. The results are also compared with those produced in the reduction performed with n-butyllithium.
