中文摘要	An incommensurate modulation was observed directly for the first time by transmission electron microscopy in a phase-separated Cu-rich La2CuO4.003 crystal at room temperature and at 93 K. After annealing in Ar atmosphere, both incommensurate modulation and phase separation disappeared. It is concluded that the incommensurate modulation is attributed to the phase separation, while the occurrence of phase separation in the sample with such a low excess oxygen content results from the enhanced antiferromagnetic interaction due to the Cu dopant.
