Abstract

Muon-spin-relaxation measurements have been performed in the overdoped regime of hole-doped high-Tc superconductor La2-xSrxCuO4 and electron-doped Pr1-xLaCexCuO4 with Cu partially replaced by Zn, in order to understand the role of stripe pinning to the superconductivity. It has been found that dynamically fluctuating stripes of spins and charges probably exist in a wide range of hole concentration in the hole-doped cuprates and that it is possible that they play an important role in the appearance of superconductivity. On the other hand, no clear symptom of stripe pinning has been observed in the electron-doped cuprates.
