초록

A top seed melt growth method was adapted to grow a 4 x 4 x 1.5 cm(3) YBa2Cu3O7-delta single crystal. We cut this single crystal into five different parts and investigated the critical current density while applying a magnetic field perpendicular to the CuO2 plane. The information extracted from five different spots showed no significant J(c) difference except at the center and the corners. The measured Jc, on the order of 10(6) A/cm(2) for H = 0 at 5 K, was remarkably high, which indicated that this large crystal could be very useful for large-scale applications such as superconducting bearings or fly-wheel systems.
