The effects of substitution of Y or Bi on the low-temperature structural phase transition, electronic anomaly and superconductivity have been studied in La2-y-xYyBaxCuO4, La2-y-xBiyBaxCuO4 and La1.9-y-xTb0.1BiySrxCuO4 with x = 1/8. Moreover, an electronic anomaly, which is analogous to those observed in La2-xBaxCuO4 and La1.6-xNd0.4SrxCuO4 with x ∼ 1/8, has been found below about 60 K in the thermoelectric power measurements for the Zn-substituted La2-xSrxCu1-yZnyO4 with x ∼ 0.115 and y = 0.01 - 0.02. These experimental results support the conclusions by Tranquada et al. that static order of the stripe correlations of holes and spins, owing to pinning by the low-temperature structure or impurities (Zn in this case), is the origin of the electronic anomaly, leading to the suppression of superconductivity.
