摘要：

A large temperature -gradient technique for growing BSCCO single crystals is reported. For comparison we also report the growth of YBCO single crystals using the same technique. BSCCO crystals grown using different cooling rates have been characterised using x-ray diffraction, TEM, SEM, AFM and optical microscopy. We find that the cooling -rate must be related to the crystal growth -rate to obtain good quality crystals. We discuss the growth mechanism and resulting growth steps, dislocation networks, transition temperature and anomalous magnetisation..
