摘要：
The homogeneity of a large YBa2Cu3O7-delta (YBCO) sample fabricated by top-seeded melt-growth has been studied in details. It was particularly shown how structural imperfections and superconducting properties are distributed along the growth front. These distributions are hard to explain within the flat a-growth front suggestion. These are better fitted by the growth scenario when the a-growth fronts seem concave and consist of small growth steps. (C) 2002 Elsevier Science B.V. All rights reserved.
