Abstract
YBCO sintered samples have been hydrogenated using chemical absorption. Exp erimental measurements of the ac higher harmonic susceptibility versus freq uency of applied magnetic field have been performed. Increasing of pinning potential Up and critical current J(c) due to the adsorbed hydrogen has bee n found. An increasing of 5% in J(c) and U-p has been quantitatively measur ed using the non-linear magnetic diffusion equation.
