N2 - La0.7Sr0.3MnO3 (LSMO) is one of the most fascinating strongly correlated oxides in which the spin polarization and magnetic property are sensitive to strain, especially in the (111)-oriented LSMO. In the paper, epitaxial LSMO(111) thin films with different thicknesses were prepared, and they showed continuous dislocation defect arrays with thickness greater than 45 nm. Then, the thick LSMO(111) films were divided into a double-layer structure with two slightly different oriented cells. The LSMO(111) films present a stronger lattice-spin coupling, thus the double-layer structure triggers an obvious magnetic heterogeneity phenomenon (magnetic bi-states) by the way of creating a double-mode ferromagnetic resonance (FMR) spectrum. Therefore, the nanostructures, especially the ordered structure defects, may trigger enriched physical phenomena and offer new forms of spin coupling and device functionality in strain-sensitive strongly correlated oxide systems.
