Abstract

Long-period structures with 32- and 36-fold periodicity to the original unit lattice distance were observed in a perovskite manganese oxide (Formula presented)(Formula presented)(Formula presented) at around 130 K, in addition to the one with fourfold periodicity. Quantitative electron diffraction profiles were measured for the long-period structure, where the intensity of superlattice reflections was observed to increase with increasing scattering angle due to static strain. This result gave a reasonable explanation for occurrence of the charge ordering of (Formula presented) and (Formula presented) ions, which was responsible for the creation of the long-period structures in (Formula presented)(Formula presented)(Formula presented).
