Self‐assembled multiferroic nanostructures with controllable morphologies are obtained by varying the stress state in epitaxial composite films containing ferrimagnetic CoFe 2 O 4 and ferroelectric PbTiO 3 . The stress state can be controlled by using different substrate orientations and phase fractions. The figure shows the transition from CoFe 2 O 4 magnetic nanorods embedded in a ferroelectric PbTiO 3 matrix (a) to PbTiO 3 ferroelectric nanorods in a CoFe 2 O 4 matrix (b).
