Abstract

A systematic muon-spin-relaxation study in Bi-2201 high-Tc cuprates has revealed that the Cu-spin correlation (CSC) is developed at low temperatures below 2 K in a wide range of hole concentrations where superconductivity appears. The CSC tends to weaken with increasing hole concentration. Moreover, CSC has been enhanced through the 3% substitution of Zn for Cu. These results are quite similar to those observed in La-214 high-T c cuprates. Accordingly, it has been suggested that the intimate relationship between the so-called spin-charge stripe correlations and superconductivity is a universal feature in hole-doped high-Tc cuprates. Furthermore, an apparent development of CSC, which is suppressed through the Zn substitution oppositely, has been observed in nonsuperconducting heavily overdoped samples, which is argued in the context of a recently proposed ferromagnetic state in heavily overdoped cuprates.
