Abstract: PURPOSE:To obtain a large-sized single crystal superconductor by growing a seed crystal at the center by such means as to stereoscopically alter rare earth element (RE) components from the center of a lamellarly formed intermediate form toward its periphery to inhibit crystal nucleus development other than from the seed. CONSTITUTION:A lamellar intermediate form M is first formed stereoscopically so that the temperature of REBa2Cu3O7-x(123) phase development (Tf) is successively reduced from the central form 1a toward the peripheral forms 1b, 1c. The form M is then put to a semi-molten state followed by inoculating its center with a seed crystal 2 and then annealing the form M at a cooling rate o <=20 deg.C/hr to a temperature: Tf minus 30 deg.C to grow the crystal 2. Thence, the resulting form is subjected to oxygen addition treatment at 200-800 deg.C in an oxidative atmosphere to bring the x-value in the REBa2Cu3O7-x phase to <=0.2, thus obtaining the objective superconductor having a texture with the REBa2Cu3O7-x phase dispersed finely in the single crystal-like 123 phase.
