摘要：

Hydrogen-charged YBa2Cu3O7 samples were investigated by muon spin rotation (mu-SR) and Hall-effect measurements. Both experiments show consistently that the charge carrier concentrations-the superconducting carriers in case of the mu-SR experiment and the normal state carriers in case of the Hall measurement-are strongly reduced by hydrogen doping. Extrapolating the initial rate of reduction, we deduce that approximately 0.8 H atoms per unit cell are needed to eliminate all carriers.
