Title:
タリウム系超電導線
Document Type and Number:
Japanese Patent JP3567003
Kind Code:
B2
Abstract:
In order to provide a crystal oriented high quality thallium group superconducting wire having a high critical current density, a thallium group superconducting film (2) is formed on an oxide single crystal fiber (1) having plane facets (3) and a polygonal cross section in the thallium group superconducting wire, wherein the c-axis of the thallium group superconducting film (2) is oriented perpendicularily, and a- and b-axis are oriented in parallel to the longitudinal direction of the above fiber (1),respectively, and resulting to obtain a high quality thallium group superconducting wire with Jc of 10<5>A/cm<2> or more at 77K.
