摘要：

Muon spin rotation(mu SR) is applied to La2_xBaxCuO4 around x = 0.12 where the superconductivity (SC) is suppressed remarkably. The magnetic ordering of Cu-moments appears below 35 K in the narrow range of x where a lattice instability from the low temperature orthorhombic (LTO) to the low-temperature tetragonal (LTT) structure exists. The present study suggests strongly that the magnetic ordering of Cu-moments is an important factor in the suppression of high-T-c superconductivity around x = 0.12 in La2-xBaxCuO4. Similar results are obtained for the La2-xSrxCUO4 and La2-x-ySrxNdyCuO4 systems.
