Abstract

Anomalies in the thermoelectric power and the Hall coefficient, which are analogous to those observed in La2-xBaxCuO4 with x ∼ 1/8, have been observed in the Zn-substituted La2-xSrxCu1-yZnyO4 with x = 0.115 and y = 0 - 0.025 and with x = 0.15 and y ∼ 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 La2-xSrxCu1-yZnyO4 with x ∼ 0.115 is likely to be attributed to this static order.
