Y1Ba2Cu3O7 (YBCO) sintered pellets have been loaded at room temperature with hydrogen by means of electrolysis in an aqueous solution (LiOH 0.3 N) with μs current pulses. The superconducting features of loaded samples have been measured as a function of the temperature by the ac magnetic susceptibility. In some conditions the YBCO pellets exhibited an enhancement of the transition temperature up to 95.4 K without a significant weakening of the superconducting grain coupling. These effects appear to be strongly dependent on the loading conditions.

Abstract
Y1Ba2Cu3O7 (YBCO) sintered pellets have been loaded at room temperature with hydrogen by means of electrolysis in an aqueous solution (LiOH 0.3 N) with μs current pulses. The superconducting features of loaded samples have been measured as a function of the temperature by the ac magnetic susceptibility. In some conditions the YBCO pellets exhibited an enhancement of the transition temperature up to 95.4 K without a significant weakening of the superconducting grain coupling. These effects appear to be strongly dependent on the loading conditions.File in questo prodotto:
