Summary

MILLIMETER-SIZED CRYSTALS OF THIS SUPERCONDUCTOR WERE FORTUITOUSLY GROWN WHILE SINTERING A FLAT DISK. IT WAS POSSIBLE TO SEPARATE INDIVIDUAL CRYSTALS FROM THE SINTERED MASS AND MEASURE THEIR PROPERTIES. THE RESISTIVE TRANSITION AND ONSET OF MAGNETIC TRANSITION OF A SINGLE CRYSTAL WAS 93 K AND THE RESISTIVE TRANSITION WIDTH WAS LOWER THAN 1 K. CRYSTALS SHOWED UNUSUAL GROWTH FEATURES. THEY WERE HEAVILY CORRUGATED ALONG THE PART OF THE CRYSTAL THAT GREW PARALLEL TO THE TOP SURFACE OF THE DISK AND THAT COINCIDED WITH THE C AXIS OF THE UNIT CELL. CRYSTALS WERE CHARACTERIZED BY X-RAYS, ELECTRON MICROSCOPY AND OPTICAL MICROSCOPY.
