Abstract

Electrical resistivity, Hall coefficient, superconducting critical magnetic field and magnetic susceptibility are measured for crystals and sintered specimens nominally described as Bi1-xLaxSrCuOy. The compounds with x=0.0 exhibit midpoint superconducting transition temperatures of 7-9K, while the other compounds exhibit higher midpoint values of 16-20K. It is found that the present system has the characteristic features of low hole carrier concentration, two-dimensional electrical conduction and anisotropic susceptibility, which are similar to those of well-known high-Tc superconductors (La1-xSrx)2CuO4 and YBa2Cu3O7.
