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 J_C 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, T_C, slightly decreases from 93.5 K to 91.5 K. The experimental results show that the accumulation of the nano-particle inclusions may improve J_C of the specimens.
