Abstract

Single domain superconductor GdBa2Cu3O 7-δ bulks with variable additions of (ZnO + ZrO 2 + SnO2) nano-particles was prepared in air by using top seed melt-textured growth process. The effect of nano-particle additions on superconductivity properties has been investigated. An enhancement of the critical current JC in low and intermediate field at 77 K and trapped field was discovered by the additions of the nano-particles. At the same time, the superconductor transition temperature, TC, slightly decreases from 93.5 K to 91.5 K. The experimental results show that the accumulation of the nano-particle inclusions may improve JC of the specimens.
