- 論文の詳細を見る
The oxygen controlled melt growth process for the filamentary Nd123 superconductor produced by solutions pinning to obtain a high J_c was examined. The filaments have been prepared by dry spinning through a homogeneous aqueous solution containing mixed acetates of Nd, Ba and Cu, poly(vinyl alcohol) and organic acids. By controlling the starting compositions and the melt growth process, a high T_c of 94.5 K and a high J_c of more than 1.3 × lO^4 A/cm^2 at 77 K and O T were achieved for the filamentary Nd_<1.18>Ba_<2.12>Cu_<3.09>O_x. superconductor with a diameter of 60 μm. The grains in the sample are not always aligned along the fiber length.
