Abstract
An approach for a rational design of self-assembled multiferroic nanostructures with controlled phase morphologies was demonstrated using the 3-D epitaxial CoFe2O4-PbTiO3 films grown on single-crystal SrTiO3 substrates. The transverse nanostructures featuring either isolated PbTiO3 in the CoFe2O4 matrix or vice versa, as well as the lamellar- and labyrinth-like arrangements of these two phases were obtained by modifying the stress conditions in the films via the appropriate choice of the substrate orientations and phase fractions. The experimental results supported the theoretical predictions which assumed the morphologies to be dictated by minimization of the sum of elastic and interfacial energies.
