摘要：

The electrical resistivity and the static magnetic susceptibility of Bi2Sr1.6La0.4CuOy were studied as a function of the hole concentration by varying the oxygen content y. An increase of the superconducting transition temperature from 23.2 K to 30.6 K is observed when the oxygen content is reduced by only 0.5% from y = 6.32 to y = 6.29. Reduction of the oxygen content also results in a sizeable decrease in both the electrical conductivity and the magnetic susceptibility in the normal state. These results emphasize the sensitivity of the superconducting and normal state properties of Bi2Sr2-xLaxCuOy to the oxygen concentration.
