A HRTEM study of the Ruddlesden-Popper compositions Sr2LMn2O7 (Ln = Y, La, Nd, Eu, Ho)
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...
