摘要

A method and an apparatus for fabricating single crystals of superconducting ceramics are described. A powedered row oxide mixture is placed and molten in a melting pot. The surface of the molten mixture is approximately at the freezing point of the mixture. From the surface, a single crystal is pulled in accordance with the known pulling crystal technique. The pulled mixture is subjected to a magnetic field normal to the pulling direction. By virtue of the magnetic field, single crystal superconducting oxide ceramics can be obtained without twin crystals.
