摘要：

The muon spin rotation (mu+SR) and NMR measurements provides clear evidences of the antiferromagnetic order of Cu-moment below 35 K for La2-xBaxCuO4 and below 15 K for La2-xSrxCuO4 in the narrow range of x where the high-T(C) superconductivity (SC) is suppressed remarkably. The results suggest that the freezing of spin fluctuations of Cu-moment is relevant to the local suppression of SC under an change of the electronic state coupled with the lattice instability.
