Abstract
At room temperature, the lattice image of a modulated structure associated with charge ordering has been observed in the (La0.5Mn0.5)MnO3 phase of La0 .9Sn0.1MnO3, which is composed of two-type phases: ABO(3) and A(2)B(2)O(7). Results of electron energy loss spectroscopy and energy dispersive x-ray s pectroscopy show that the need of the chemical balance and small A-site rad ius for the (La0.5Mn0.5)MnO3 phase are the main reasons for the appearance of charge ordering stripes.
