Abstract Muon spin rotation (μSR) is applied to La2−x Ba x CuO4 aroundx=0.12 where the superconductivity (SC) is suppressed remarkably. The magnetic ordering of Cu-moments appears below 35 K in the narrow range ofx 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 aroundx=0.12 in La2−x Ba x CuO4. Similar results are obtained for the La2−x Sr x CuO4 and La2−x−y Sr x Nd y CuO4 systems.
