Strong interfacial magnetic coupling in epitaxial bilayers of LaCoO3/LaMnO3 prepared by chemical solution deposition. Thin Solid Films, 553(28), 81-84. https://doi.org/10.1016/j.tsf.2013.11.0600040-6090https://hdl.handle.net/10347/45746We report the synthesis of high quality epitaxial bilayers of LaMnO3/LaCoO3 (LCO/LMO) on (001) LaAlO3, by spin-coating of a polymeric aqueous solutions. The bilayer shows a very large increase of the magnetization coercive field (≈ 3000%) with respect to the isolated LMO or LCO films. We suggest that the origin of this effect is a strong Mn4 +–O–Co2 + exchange interaction at the interface. Our results demonstrate that a simple chemical method is able to produce high quality epitaxial heterostructures in which interfacial effects can modify substantially the properties of the individual layersengAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Polymer assisted depositionThin-filmsInterfacial exchangeInvestigaciónjournal article10.1016/j.tsf.2013.11.060open access
