Abstract

We have recently argued that manganites do not possess stripes of charge order, implying that the electron-lattice coupling is weak [Loudon, Phys. Rev. Lett. 94, 097202 (2005)]. Here we independently argue the same conclusion based on transmission electron microscopy measurements of a nanopatterned epitaxial film of La0.5 Ca0.5 Mn O3. In strain relaxed regions, the superlattice period is modified by 2% to 3% with respect to the parent lattice, suggesting that the two are not strongly tied.
