The microstructure of manganite thin films on titanate substrates, fabricated by means of liquid chemical vapor deposition, was studied using transmission electron microscopy. Both materials had a perovskite structure, with a lattice misfit of about 1%, but there was no evidence of a correlation between the misfit dislocation density and the misfit. In the vicinity of the interface, the misfit was accommodated by a distortion of the manganite lattice. In regions which were not adjacent to the interface, small particles (identified as MnO) were found to be associated with the misfit. The MnO phase was unstable with respect to the manganite. The growth of thin films of manganite on titanate was epitaxial, with an orientational relationship of (100)manganite||(100)titanate||(100)MnO and [010]manganite||[010]titanate||[010]MnO. The interface was composed of Ti and Mn atoms; plus O.
