Bi-Pb-Sr-Ca-Co-O Superconducting Fibers Drawn from Melt-Quenched Glass Preforms

概要

論文の詳細を見る
Bi-Pb-Sr-Ca-Cu-O glass fibers were drawn from melt-quenched glass preforms by the method that is ordinarily applied to optical fiber fabrication. The drawn fibers were very flexible, and their surfaces were smooth. The glass fibers were crystallized by annealing and had superconducting properties. The annealed (1133K, 240hour) Bi_<1.6>Pb_<0.4>Sr_2Ca_2Cu_3O_x fiber exhibited superconductivity with a T_c (zero) of 68 K and a critical current density (30 K, zero magnetic field) of 22 A/cm^2.
