Independent Control of the Magnetization in Ferromagnetic La2/3Sr1/3MnO3/SrTiO3/LaCoO3 Heterostructures Achieved by Epitaxial Lattice Mismatch 2016 Access copy available to the general public Unrestricted We report the effect of interface symmetry-mismatch on the magnetic properties of LaCoO3 (LCO) thin films. Growing epitaxial LCO under tensile strain on top of cubic SrTiO3 (STO) produces a contraction along the c axis and a characteristic ferromagnetic response. However, we report here that ferromagnetism in LCO is completely suppressed when grown on top of a buffer layer of rhombohedral La2/3Sr1/3MnO3 (LSMO), in spite of identical in-plane and out-of-plane lattice deformation. This confirms that it is the lattice symmetry mismatch and not just the total strain, which determines the magnetism of LCO. On the basis of this control over the magnetic properties of LCO, we designed a multilayered structure to achieve independent rotation of the magnetization in ferromagnetic insulating LCO and half-metallic ferromagnet LSMO. This is an important step forward for the design of spin-filtering tunnel barriers based on LCO. info:eu-repo/grantAgreement/EC/FP7/312483/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM 2 info:eu-repo/grantAgreement/ES/MINECO-FEDER/MAT2014-51982-C2-2-R info:eu-repo/grantAgreement/ES/MINECO/MAT2013–44673-R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 12.712 2016 CHEMISTRY, PHYSICAL 7 / 144 = 0.049 2016 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 11 / 273 = 0.04 2016 Q1 T1 NANOSCIENCE & NANOTECHNOLOGY 5 / 85 = 0.059 2016 Q1 T1 PHYSICS, CONDENSED MATTER 7 / 67 = 0.104 2016 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 11 / 164 = 0.067 2016 Q1 T1 PHYSICS, APPLIED 7 / 147 = 0.048 2016 Q1 T1 7.892 2016 Bioengineering 2016 Q1 Chemistry (miscellaneous) 2016 Q1 Nanoscience and Nanotechnology 2016 Q1 Materials Science (miscellaneous) 2016 Q1 Mechanical Engineering 2016 Q1 Condensed Matter Physics 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Lucas, I.
