Beschreibung
Zusammenfassung:YBCO sintered samples have been hydrogenated using chemical absorption. Experimental measurements of the ac higher harmonic susceptibility vs frequency of applied magnetic field have been performed. Increasing of pinning potential Up and critical current Jc due to the adsorbed hydrogen has been found. An increase of 5% in Jc and Up has been quantitatively measured using the non-linear magnetic diffusion equation. 7 refs.
