Abstract
Based on the top seeded infiltration and growth technique (TSIG), a novel configuration was employed to fabricate single-domain Gd-Ba-Cu-O (GdBCO) bulk superconductors. And the morphology, microstructure, and superconducting properties of the products were investigated in detail. The results indicate that, employing the novel configuration can increase the supporting ability of the liquid source pellet, and the slope or collapse of the sample during the heat treatment process can be effectively avoided, thus the stability and repeatability of the experiments are advanced. In addition, the novel configuration also contributes to the complete growth of the whole bulk.
