Abstract

The so-called 1/8 effect, namely, the anomalous suppression of superconductivity at the hole concentration per Cu in the CuO₂ plane, p, ∼ 1/8 has been investigated in the partially Zn-substituted Bi-2212 and Y-123 phases by measuring the Hall effect and the muon spin relaxation (μSR ). The Hall angle has been found to exhibit large enhancement at p ∼ 1/8 in Bi₂Sr₂Ca_1-xY_x(Cu _1-yZn_y)₂O_8+δ with y = 0.025. In YBa₂Cu_3-2yZn_2yO_7-δ with y = 0.025, anomalous enhancement of the muon spin depolarization has been observed at p ∼ 1/8, indicating that the magnetic correlation between Cu spins is enhanced at p ∼ 1/8. These results support the stripe model and the proposition that the 1/8 effect is common to all high-T_c cuprates with the CuO₂ plane.
