Further Enhancement of the Critical Temperature up to 105 K of Hydrogen Loaded YBCO Melted Samples by μs Pulsed Electrolysis

In this paper we report results about enhancement of the transition temperatures of Y_1 Ba_2 Cu_3 O_7-δ melted samples hydrogen loaded (H-YBCO) with high power μs pulsed electrolysis. The fundamental AC magnetic susceptibility has been measured as a function of the temperature for different frequency values of the exciting magnetic field. The H-YBCO sample exhibited a magnetic onset temperature (T_on) as high as 105K. The susceptibility behavior below the Ton shows significant change of shape. Results, previously reported, on a sintered YBCO pellets have been reproduced using melted YBCO samples.
