The effect of substrate orientation of the morphologies of epitaxial self-assembled nanostructures was demonstrated using newly synthesized multiferroic 0.67PbTiO3-0.33CoFe2O4 nanocomposite thin films. The two-phase nanostructures were grown on single crystal SrTiO3 substrates having (001) and (110) orientations using pulsed laser deposition. The nanostructures of both orientations consisted of vertical rod- or platelet-like columns of CoFe2O4 dispersed in the PbTiO3 matrix. For the (001) orientation the platelet habits were parallel to the 110} planes, whereas for the (110) orientation the platelets were parallel to the 111} planes. The differences in the platelet orientations were explained using a thermodynamic theory of heterophase structures.
