<P>Epitaxial strain imposed in complex oxide thin films by heteroepitaxy is recognized as a powerful tool for identifying new properties and exploring the vast potential of materials performance. A particular example is LaCoO<SUB>3</SUB>, a zero spin, nonmagnetic material in the bulk, whose strong ferromagnetism in a thin film remains enigmatic despite a decade of intense research. Here, we use scanning transmission electron microscopy complemented by X-ray and optical spectroscopy to study LaCoO<SUB>3</SUB> epitaxial thin films under different strain states. We observed an unconventional strain relaxation behavior resulting in stripe-like, lattice modulated patterns, which did not involve uncontrolled misfit dislocations or other defects. The modulation entails the formation of ferromagnetically ordered sheets comprising intermediate or high spin Co<SUP>3+</SUP>, thus offering an unambiguous description for the exotic magnetism found in epitaxially strained LaCoO<SUB>3</SUB> films. This observation provides a novel route to tailoring the electronic and magnetic properties of functional oxide heterostructures.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/nalefd/2012/nalefd.2012.12.issue-9/nl302562f/production/images/medium/nl-2012-02562f_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nl302562f'>ACS Electronic Supporting Info</A></P>
