The fabrication of large single-grain RE-Ba-Cu-O (RE denotes rare earth elements) is essential for bulk applications. In the present study, we report on a hot-seeding method for growing Nd-Ba-Cu-O with Nd123 seed crystals. We made an arrangement, in which the Nd123 seed crystal can be transported to the centre of the furnace with a rod through a hole in a rubber cork and insulating stopper. The seed was placed in a small dip made in the rod, which can be turned to drop the seed on the sample. The advantage of this method is that perturbation in the growth conditions such as temperature and oxygen partial pressure can be minimized. Using this method we could grow large single-domain c-axis-oriented samples with the surface area larger than 3 cm × 3 cm.
