ABSTRACT
Magnetization measurements of powder and sintered samples of Ba2Y1Cu3O9-y have been made at 77 K. Excellent critical current densities Jc’s of about 3×104 A/cm2 at 10 kOe were estimated for the powder samples, which consisted of single-crystal particles of ∼3 μm in dimension. These Jc’s were about two orders of magnitdue larger than those of the sintered sample.

    The superconducting current density, Jc, of Y1Ba2Cu3O7-δ (YBCO) is greatly influenced by hole doping levels. Hole doping is mainly dominated by oxygen ordering, so the postannealing process is one of the essential factors for practical applications of YBCO superconductors. However, little...
