Preparation and Properties of Single Crystals of the High-T_c Oxide Superconductor in the Bi-Sr-Ca-Cu-O System : Electrical Properties of Condensed Matter

概要
- 論文の詳細を見る
Single crystals of the superconductor in the Bi-Sr-Ca-Cu-O system were prepared by the Bridgman method. Platy crystals annealed at various physical conditions were examined by electrical resistivity measurements and single crystal X-ray diffraction studies. The superconducting transition temperature (T_c) depended on the annealing temperatures and oxygen pressure. Corresponding to annealing conditions, single crystal X-ray diffraction patterns on (hk1)* Layer precession photographs systematically changed at room temperature. This may be related to the slight differences of the cell parameters of each specimen.
