Abstract

The modulated crystal structure of Sr_0.35CoO₂ is studied by electron diffraction measurement and high-resolution electron microscopy. Sr_0.35CoO₂ consists of two interpenetrating subsystems of CoO₂ sheets and intercalated Sr layers. Both subsystems have common a- and c-axes with a = 4.80 Å and c = 11.33 Å. The two subsystems of Sr_0.35CoO₂ are mutually commensurated parallel to the b-axis, i.e., b₁ = 2.80 Å for the CoO ₂ sheets and b₂ = 8.41 Å for the intercalated Sr layers, showing that the axial b₁/b₂ ratio is 1/3, i.e., rational. The high-resolution images taken with the incident electron beams parallel to the a-, b-, and c-axes clearly exhibit characteristic atomic arrangements.
