In doped manganites, a superlattice (SL) modulation associated with charge/orbital ordering is accepted as a key component in understanding many intriguing properties. It has been reported that the SL modulation always appears on the a axis of the crystals. Here in this study, by using multiple transmission electron microscopic techniques, we observe a type of anomalous nanocluster in which the SL modulation appears on the c axis of La1/3Ca2/3MnO3. By correlating the thermal evolution of the anomalous nanoclusters to other property measurements, we suggest that strain is responsible for the formation of the anomalous nanoclusters. The phase separation and phase transition scenario in La1/3Ca2/3MnO3 are also described using electronic-liquid-crystal (ELC) phases. Lastly, an ELC phase diagram in La1/3Ca2/3MnO3 is constructed as a function of temperature based on our observations.
