Abstract :Bi-2212 superconducting single crystal insert ignore into journalissuearticles values(nano); whiskers have been fabricated by annealing a melt-quenched insert ignore into journalissuearticles values(glass); Bi3Sr2Ca2Cu3Ox precursor. A couple of insert ignore into journalissuearticles values(nano); Whiskers obtained were placed crosswise on a YSZ single crystal substrate and then heat treated at 830 C for 25 minute to form nano-scale junction. The Tc of each nano-whisker was found to be 85 K and the critical current density, Jc, of the whiskers was calculated to be 1177 Acm-2 at zero field. The I-V characteristics of the nano-junction at 30 K were found to show a multiple-branch structure, which is the main behavior of the Josephson junction.
