Journal ArticleDOI
Melt processing for obtaining NdBa2Cu3Oy superconductors with high Tc and large Jc
TL;DR: In this paper, a dc magnetization measurement of Nd1+xBa2−xCu3Oy (Nd123) superconductors was performed in a reduced oxygen atmosphere.
Journal ArticleDOI
Melt-processed light rare earth element - Ba - Cu - O
TL;DR: In this article, the microstructural and superconducting properties of light rare earth elements (LREs) are reviewed and the flux pinning mechanism is also discussed, on the basis of their study over the last several years, the melt processes for LRE - Ba - Cu - O are described.

TL;DR: In this paper, the authors showed that rare earth (RE) ions with large radii exhibit relatively low T c due to the presence of RE-Ba solid solution and that this solid solution can be suppressed if these superconductors are melt processed in a reduced oxygen atmosphere.
