摘要：

Positive muon spin rotation (mu+SR) is applied to La2-xBaxCuO4 around x=0.12, where superconductivity is suppressed remarkably. The magnetic ordering of Cu-moments appears below 35 K in the narrow range of 0.11 less-than-or-equal-to x less-than-or-equal-to 0.135, where the transition 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 plays an important role in the suppression of the high-T(c) superconductivity around x=0.12 in La2-xBaxCuO4.
