Abstract

The effects of substitution of Bi for La have been investigated in La2-y-xBiyBaxCuO4 (x=1/8), to clarify the correlation between the superconductivity, electronic anomaly and crystal structure at x = 1/8 in La2-xBaxCuO4. 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 Tc increases. It is concluded that the suppression of superconductivity at x = 1/8 in La2-xBaxCuO4 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 La1.6-xNd0.4SrxCuO4.
