By investigating Cu-NMR on single crystals, we have found that spatially incoherent LTT structure emerges below 50 K in the sample with x=0.12. This incoherent structure is considered to play a key role for the slight depression of the superconductivity around x=1/8.","authors_text":"A. Oosawa, J. Tonishi, K. Yamada, M. Fujita, T. Adachi, T.
