Starting from an intercalated Fe layer between the graphene and Ir(111) surface we find that graphene-substrate interaction can be fine-tuned by Fe-Ir alloying at the interface. When a critical Ir-concentration close to 0.25 is reached in the Fe layer, the Dirac cone of graphene is largely restored and can thereafter be tuned across the Fermi level by further increasing the Ir content. Indeed, our study reveals an abrupt transition between a chemisorbed phase at small Ir concentrations and a physisorbed phase above the critical concentration. The latter phase is highly reminiscent of the graphene on the clean Ir(111) surface. Furthermore, the transition is accompanied by an inversion of the graphene''s induced magnetization due to the coupling with the Fe atoms from antiferromagnetic when chemisorbed to weakly ferromagnetic in the physisorption regime, with spin polarizations whose magnitude may be tuned with the amount of Fe content. 000060676 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/FIS2013-48286-C2-1-P$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2013-46593-C6-4-P$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2013-47878-C2-R$$9info:eu-repo/grantAgreement/ES/MINECO/MAT2015-66888-C3-1R 000060676 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000060676 590__ $$a7.042$$b2017 000060676 591__ $$aMATERIALS SCIENCE, MULTIDISCIPLINARY$$b33 / 285 = 0.116$$c2017$$dQ1$$eT1 000060676 592__ $$a2.813$$b2017 000060676 593__ $$aChemistry (miscellaneous)$$c2017$$dQ1 000060676 593__ $$aCondensed Matter Physics$$c2017$$dQ1 000060676 593__ $$aMechanics of Materials$$c2017$$dQ1 000060676 593__ $$aMechanical Engineering$$c2017$$dQ1 000060676 593__ $$aMaterials Science (miscellaneous)$$c2017$$dQ1 000060676 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000060676 700__ $$aSlawinska, J. 000060676 700__ $$aAbadia, M. 000060676 700__ $$aRogero, C. 000060676 700__ $$aOrtega, J.E. 000060676 700__ $$aPiquero-Zulaica, I. 000060676 700__ $$0(orcid)0000-0003-2698-2543$$aLobo-Checa, J.$$uUniversidad de Zaragoza 000060676 700__ $$aArnau, A. 000060676 700__ $$aCerdá, J.I. 000060676 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
