Post-oxygenation under high pressure of superconducting EuBCO and GdBCO coated conductors
Abstract Treatment of GdBCO_CC under 100 bar of O 2 at 600 °C for 3 h led to an increase in J c (77K, 0 T) by 6% up to 2.67 MA/cm 2 and a decrease in the c-parameter of Gd123 to 1.17310 nm, which may be associated with its overdoping with oxygen (the charge carrier density in superconducting Gd123 layer was 6.91×10 21 cm 3 ). No strong correlation was observed between J c , T c , c-parameter of RE123 (RE=Eu, Gd) and carrier density n H of EuBCO_CC and GdBCO_CC treated at 300-800 °C, 1-160 bar O 2 for 3-12 h.
