      Silver clad wire; critical current density

    • Abstract


      Silver clad wires of highTc superconductor Y1Ba2Cu3O7−x have been fabricated through the powder metallurgy technique. The reacted wires show a midpointTc of 84K. A critical current density of 26·4 A cm−2 (77K, 0T) is obtained in these wires. The wires, however, turn complete normal only at a current density of 280 A cm−2. The reasons for low critical current density obtained in these wires are discussed.
