Abstract

A method has been developed for growing single crystals of Ba₂GdCu₃O_7−y of much larger size (∼2×3×6 mm³). The crystals as grown were semiconductors and became superconductors with a zero resistance temperature of 92 K after they were annealed in flowing oxygen. Good x‐ray diffraction and Laue patterns were obtained from a superconducting crystal (∼2×3×4 mm³) that was cleaved in (001) plane, and lattice constants were determined to be a=3.8401 Å, b=3.9007 Å, and c=11.7104 Å.
