Abstract

The effects of substitution of Bi for La have been investigated in La_2-y-xBi_yBa_xCuO₄ (x=1/8), to clarify the correlation between the superconductivity, electronic anomaly and crystal structure at x = 1/8 in La_2-xBa_xCuO₄. With increasing y, both the rhombic distortion of the CuO₄ basal plane and the anomaly in the thermoelectric power at low temperatures become small, while T_c increases. It is concluded that the suppression of superconductivity at x = 1/8 in La_2-xBa_xCuO₄ is due to the electronic anomaly in cooperation with the rhombic distortion of the CuO₄ basal plane at low temperatures, as in the case of La_1.6-xNd_0.4Sr_xCuO₄.
