A STUDY OF SUPERCONDUCTIVITY IN Y-Ba-Cu-F-O SYSTEM
-
Abstract
High temperature superconductivity, up to 258K, was observed in the Y1Ba2Cu3F2xO7-x-δ(0.2≤x≤1) bulk materials prepared by means of conventional ceramic-technique. X-ray diffraction analysis shows that these materials are multiphase. It is believed that to obtain a high Tc superconducting material with Tc near room temperature is possible. though the high Tc state of samples is now very unstable.
