By means of ab initio calculations, we find that both the high strain produced by the substrate and the presence of the free surface contribute to the stabilization of an in-plane ferromagnetic coupling, giving rise to a nonzero net magnetic moment in the ultrathin films. Coupled with this change in the magnetic order we find an insulatormetal transition triggered by the quantum confinement and the tensile epitaxial strain. Accordingly, our magnetic measurements in 3-nm ultrathin films show a ferromagnetic hysteresis loop, absent in the bulk compound due to its G-type antiferromagnetic structure. 000095554 536__ $$9info:eu-repo/grantAgreement/EC/H2020/734187/EU/Spin conversion, logic storage in oxide-based electronics/SPICOLOST$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 734187-SPICOLOST 000095554 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000095554 590__ $$a4.036$$b2020 000095554 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b130 / 333 = 0.39$$c2020$$dQ2$$eT2 000095554 591__ $$aPHYSICS, CONDENSED MATTER$$b22 / 69 = 0.319$$c2020$$dQ2$$eT1 000095554 591__ $$aPHYSICS, APPLIED$$b41 / 160 = 0.256$$c2020$$dQ2$$eT1 000095554 592__ $$a1.78$$b2020 000095554 593__ $$aElectronic, Optical and Magnetic Materials$$c2020$$dQ1 000095554 593__ $$aCondensed Matter Physics$$c2020$$dQ1 000095554 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000095554 700__ $$aBarral, M.A. 000095554 700__ $$aGraf, M.E. 000095554 700__ $$aLlois, A.M. 000095554 700__ $$0(orcid)0000-0002-1296-4793$$aAguirre, M.H.$$uUniversidad de Zaragoza 000095554 700__ $$aSteren, L.B. 000095554 700__ $$aDi Napoli, S. 000095554 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
