Abstract

In order to investigate the local structure in the CuO2 plane of the La-based high-Tc cuprate La2-xBaxCuO 4, we have carried out measurements of 63Cu-NMR on single crystals with x=0.08 and 0.10 at low temperatures down to 4 K. In both samples, the local structure deduced from observed NMR spectra agreed with the averaged structure. In high-temperature region around 300K, detailed investigation of NMR line width has shown the existence of the local structure different from the averaged structure; that is, CuO6 octahedra tilt from the c-axis toward the random direction by approximately 1.4 deg.
