23. Superconductivity of Bi2 (Sr0.9Ca0.1)2 CuOy single crystals

Author

Wang, X. L., Shang, S. X., Wang, H., Jiang, M. H., and Zhao, Z. X.

Abstract

Bi2 (Sr0.9Ca0.1)2 CuOy single crystals were grown by the self-flux method. The temperature dependence of resistance and ac susceptibility measurements showed that the as-grown crystal is semiconductive between 4.2 K and 300 K. However, after annealing in air for more than 20 days the crystal became superconducting with a Tc of 66 K obtained from the R-T curve. The ac susceptibility data also showed a strong superconducting transition at 71 K. X-ray diffraction indicated that the structure of the as-grown and the annealed crystal both are orthorhombic. The Tc of 71 K of the Bi2 (Sr0.9Ca0.1)2 CuOy crystal may be due to the increase of oxygen content in the crystal after the long-time annealing in air. It is suggested that the superconductivity of the Ca-doped 2201 phase of the Bi-based system, which up to now was found to have a Tc=7–22 K, is similar to the 2201 phase of the Tl-based system.
