Abstract

The crystal microstructure, superconductivity, and normal state transport properties of Bi_1.9+xSru_1.7-xLa_0.4CuO_6-δ(0≤ x ≤ 0.4) system were investigated by means of electron diffraction (ED), resistivity, and TEP. Analyses of the experimental results indicate that with the increase of Bi content, the incommensurate modulation wavelength decreases and the distortion of CuO₆ octahedron enhances. Increasing Bi content decreases the carrier concentration rapidly, and induces an MI transition. The destruction of superconductivity mainly derives from two aspects: the enhancement of structural distortion due to the introduction of more Bi and the variation of the carrier concentration of the system.
