概要

• 論文の詳細を見る

• The preparation condictions, formation processes and superconducting properties of the materials in a Tl-Pb-Sr-Ca-Cu-O system have been investigated. The superconducting properties are found to depend strongly on the starting composition and heating time as well as the heating temperature. There are at least two superconducting phases with T_c's at 80 and 120 K. The 80 K T_c phase is formed in a short amount of time and then changes to the 120 K T_c phase after prolonged heating periods.
