Transport and {mu}SR studies at p{approximately}1/8 in the Bi-2212 and Y-123 phases
The so-called 1/8 effect, namely, the anomalous suppression of superconductivity at the hole concentration per Cu in the CuO{sub 2} plane, p, {approximately}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 ({mu}SR). The Hall angle has been found to exhibit large enhancement at p {approximately} 1/8 in Bi{sub 2}Sr{sub 2}Ca{sub 1{minus}x}Y{sub x} (Cu{sub 1{minus}y}Zn{sub y}){sub 2}O{sub 8{delta}} with y = 0.025. In YBa{sub 2}Cu{sub 3{minus}2y}Zn{sub 2y}O{sub 7{minus}{delta}} with y = 0.025, anomalous enhancement of the muon spin depolarization has been observed at p {approximately} 1/8, indicating that the magnetic correlation between Cu spins is enhanced at p {approximately} 1/8. These results support the stripe model and the proposition that the 1/8 effect is common to all high-{Tc} cuprates with the CuO{sub 2} plane.
