| Abstract: | An ideal n=3 member of Ruddlesden Popper (RP) phase Ca4Mn3O10with a space group of I4/mmm was obtained by solid-state reaction under high pressure. This phase was studied by transmission electron microscopy. An approximate model of the structure was proposed. Simulation work was carried out based on this model, and the simulated images were compared with the experimental ones. |
