Abstract

We have fabricated c-axis oriented Nd-Ba-Cu-O superconductors with the top-seeded melt-growth technique in air. The highest Jc reached 50,000 A/cm2 at 77 K and 0.9 T. The local superconducting properties strongly depended on the distance from a seed crystal. The onset Tc as well as the transition width was improved as the distance from a seed increased. The chemical analyses revealed that the substitution levels of Nd on the Ba site gradually decreased with increasing the distance from a seed.
