摘要：

The copper oxide superconductor La2-xSrxCuO4 shows x-T(C) curve with a small dip at x=0.115. In order to investigate the origin of this kink, the temperature dependence of La-139-NMR spectra has been studied. The significant broadening in the spectra was observed below 30K, suggesting the existence of the antiferromagnetic phase transition around x=0.115.
