Title: Substitution effects on the electronic anomaly and superconductivity in La{sub 2-x}Ba{sub x}CuO{sub 4} and La{sub 2-x}Sr{sub x}CuO{sub 4} with x {approximately} 1/8

Abstract

The effects of substitution of Y or Bi on the low-temperature structural phase transition, electronic anomaly and superconductivity have been studied in La{sub 2{minus}y{minus}x}Y{sub y}Ba{sub x}CuO{sub 4}, La{sub 2{minus}y{minus}x}Bi{sub y}Ba{sub x}CuO{sub 4}, and La{sub 1.9{minus}y{minus}x}Tb{sub 0.1}Bi{sub y}Sr{sub x}CuO{sub 4} with x = 1/8. Moreover, an electronic anomaly, which is analogous to those observed in La{sub 2{minus}x}Ba{sub x}CuO{sub 4} and La{sub 1.6{minus}x}Nd{sub 0.4}Sr{sub x}CuO{sub 4} with x {approximately} 1/8, has been found below about 60 K in the thermoelectric power measurements for the Zn-substituted La{sub 2{minus}x}Sr{sub x}Cu{sub 1{minus}y}Zn{sub y}O{sub 4} with x {approximately} 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.
