摘要
Differential temperature analysis (DTA) in a magnetic field was carried out for growth of YBa2Cu3O7, in order to investigate the influence of magnetic fields up to 14T on the melt-textured growth process. The DTA peak for the heating process, which corresponds to melt transition, was insensitive to the magnetic field. For the cooling process, however, the peak corresponding to crystal formation was shifted to a lower temperature under application of a magnetic field of 14T. The shift of the DTA peak by a magnetic field is due to the lowering crystal growth rate by the magnetic field. (C) 2001 Elsevier Science B.V. All rights reserved.
