Influence of a magnetic field on melt-growth process of YBa2Cu3Ox

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 correspondin g 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.
