摘要：

Superconducting properties of the Bi2SrxCayCu3Oz system are studied in the composition range 1.2&lex&le2.2 and 2&ley&le2.4. Both resistivity and low field magnetization data are presented. Both types of measurements show the development of the 110 K phase from a low-Tc phase as the Sr content is reduced from 2.2 to 1.2. Best results are obtained for the nominal composition Bi2Sr1.6Ca2Cu3Oz. The very similar character of the resistive and inductive transition for two phase samples is attributed to interlayering of the two phases.
