High Pressure Oxygenation of EuBCO and GdBCO Coated Conductors

To study the possibility of overdoping with oxygen and, thus, an increase in the charge carrier density, nH(100 K), in RE123 layers (RE Eu, Gd) with the aim of increasing the critical current density, Jc, oxygenation was carried out in the pressure range of pO2 1160 bar and temperatures of TS 300800 C during 312 h of commercial EuBCO and GdBCO coated conductors (CC), from which the protective Cu layer and, in half of the cases, the Ag layer …
