Transport anomalies in 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: Possibility of the pinning of CDW and SDW by Zn
Anomalies in the thermoelectric power and the Hall coefficient, which are analogous to those observed in La{sub 2{minus}x}Ba{sub x}CuO{sub 4} with x {approximately} 1/8, have been observed in the Zn-substituted La{sub 2{minus}x}Sr{sub x}Cu{sub 1{minus}y}Zn{sub y}O{sub 4} with x = 0.115 and y = 0 {minus} 0.025 and with x = 0.15 and y {approximately} 0.02. Based on the so-called stripe model, these are explained as being due to the formation of the static order of the stripe-patterned CDW and SDW on account of the pinning by Zn. Accordingly, the long-standing problem on the conspicuous suppression of superconductivity in 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 is likely to be attributed to this static order.
