YBaCuO superconductive thick film wires were fabricated by employing a melt process with a peak temperature of 1100 °C. Transition temperature and peak critical current density of these YBaCuO superconductive thick film wires were 90 K and 3.5 × 10⁴ A/cm², respectively. Their magnetic lev-itation force measured at a temperature of 77 K with a permanent magnet was 65.45 N during magnetic cooling. The repulsion force in the case of field cooling was 10.12 N. A permanent magnet with surface magnetism of 5.25 kG was used to cool down superconductive specimens, from which magnetic force of 15.62% of peak magnetic field was trapped. A single crystal YBaCuO superconductive thick film wire was obtained after coating powders of raw materials from a melt process employed for the fabrication of YBaCuO superconductive thick film wire.
