Abstract

YbBa₂Cu₃O_7-x (Yb123) bulk superconductors were prepared by a melt growth process under various oxygen partial pressures. The microstructure of melt-processed Yb123 was observed by scanning electron microscopy and optical microscopy. T_c and critical current density (J_c) were measured with a SQUID magnetometer. The size of Yb₂BaCuO₅ particles in the YbBa₂Cu₃O_7-x phase was about 1 to 10 μm. The melt processed Yb123 sample showed T_c^onset of 91.5 K and J_c of 50,000 A/cm² at 77 K and 0 T.
