✦ Synopsis

The details of crystal structures in La2_xSrxCuO4 with x of about 0.115 have been exami~ d by electron diffraction in a temperature range between room temperature and 15 K. In addition to an FTto-LTO transition, a low-temperature transition at 104 K was experimentally found only in x = ~,15.

1 ½0-type superlattice spots also appear at the transition. An or~_n of

In electron diffraction patterns, the superlattice spots is simply discussed in relation to a To-suppression observed in La-Sr-Cu-O.
