Controlling the Electrical and Magnetoelectric Properties of Epitaxially Strained Sr1- xBaxMnO3 Thin Films 2017 Access copy available to the general public Unrestricted The perovskite (Sr, Ba)MnO3 system is an ideal candidate for tailoring electrical and magnetoelectric properties through the accurate control of Ba content and epitaxial strain due to the strong coupling between polar instability, spin order, and lattice. Here, first, the polar order is proved to be induced in Sr1- xBaxMnO3 thin films through lattice expansion either by epitaxial strain or chemical pressure, which correlates with the evolution of the dielectric properties. Second, due to strong spin–phonon coupling, a large magnetoelectric response is found in the (Sr, Ba)MnO3 system, in which the dielectric constant drops up to 50% when the antiferromagnetic order emerges, larger than most magnetoelectric oxides. More important, this coupling between magnetism and dielectric properties can be tuned from ˜18% to ˜50% by appropriately selecting Ba content and epitaxial strain. Third, a clear trend of increasing the band gap energy on increasing the unit cell volume either by epitaxial strain or chemical pressure is found, which opens the way for engineering the semiconducting properties of (Sr, Ba)MnO3 system at will. Thus, this work proves the possibility to design the electrical response and the magnetoelectric coupling in (Sr, Ba)MnO3 system. info:eu-repo/grantAgreement/ES/MINECO/MAT2014-51982-C2 info:eu-repo/grantAgreement/EC/FP7/312483/EU/Enabling Science and Technology through European Electron Microscopy/ESTEEM 2 info:eu-repo/grantAgreement/ES/DGA/E26 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.834 2017 CHEMISTRY, MULTIDISCIPLINARY 40 / 171 = 0.234 2017 Q1 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 49 / 285 = 0.172 2017 Q1 T1 1.796 2017 Mechanics of Materials 2017 Q1 Mechanical Engineering 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-6487-1505 Maurel, L.
