- High resolution transmission electron microscopy has been used to probe the microstructure of then=2 Ruddlesden-Popper manganates Sr2LnMn2O7(Ln=Y, La, Nd, Eu, Ho). Intergrowths ofn=1 (K2NiF4) are observed only forLn=La. Intergrowths withn≥5, essentially perovskite microdomains, are seen in the other compositions. The density of perovskite regions is greatest near the edges of the thin specimens, with then=2 structure becoming established in the bulk. The complementarity of HRTEM and neutron diffraction is discussed. © 1998 Academic Press.
