Title: Anomalous nanoclusters, anisotropy, and electronic nematicity in the doped manganite L a 1 / 3 C a 2 / 3 Mn O 3

Abstract

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 La 1/3Ca 2/3MnO 3. 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 La 1/3Ca 2/3MnO 3 are also described using electronic-liquid-crystal (ELC) phases. Lastly, an ELC phase diagram in La 1/3Ca 2/3MnO 3 is constructed as a function of temperature based on our observations.
