Abstract

For the cold seeded melt growth of RE-Ba-Cu-O, it is important to decompose the precursor completely without melting the Nd-Ba-Cu-O seed crystal. We have studied the variation of growth mode with the maximum holding temperature (Tmax) and the holding time for Y and Gd systems. Growth modes were changed by Tmax and classified into four groups. In the case of Gd system, the temperature window for single-domain growth was narrow compared with Y system. This is ascribed to the fact that the decomposition temperature of Gd system is close to that of Nd123 seed crystal.
