摘要：

A single-step partial melting procedure without temperature gradient on the sample was developed. The YBa2Cu3O7-delta platelets can be grown with their a-b planes almost parallel in the centimetre range. Morphological observations of regularly oriented macrospirals on the as-grown (001) surface suggest a screw dislocation growth mechanism along the c axis of the platelets.
