Chemical design provides atomically precise control of the π-electron cloud, which makes them promising for nanoscale magnetic devices. However, direct verification of their spatially resolved spin-moment remains elusive. Here, we report the spin-polarization of chiral graphene nanoribbons (one-dimensional strips of graphene with alternating zig-zag and arm-chair boundaries), obtained by means of spin-polarized scanning tunnelling microscopy. We extract the energy-dependent spin-moment distribution of spatially extended edge states with π-orbital character, thus beyond localized magnetic moments at radical or defective carbon sites. Guided by mean-field Hubbard calculations, we demonstrate that electron correlations are responsible for the spin-splitting of the electronic structure. Our versatile platform utilizes a ferromagnetic substrate that stabilizes the organic magnetic moments against thermal and quantum fluctuations, while being fully compatible with on-surface synthesis of the rapidly growing class of nanographenes. 000131440 536__ $$9info:eu-repo/grantAgreement/ES/AEI/CEX2020-001058-M$$9info:eu-repo/grantAgreement/ES/AEI/PID2019-107338RB-C61$$9info:eu-repo/grantAgreement/ES/AEI/PID2019-107338RB-C62$$9info:eu-repo/grantAgreement/ES/AEI/PID2019-107338RB-C63$$9info:eu-repo/grantAgreement/ES/AEI/PID2019-107338RB-C64$$9info:eu-repo/grantAgreement/ES/DGA/E12-20R$$9info:eu-repo/grantAgreement/ES/DGA/E13-20R$$9info:eu-repo/grantAgreement/EC/H2020/863098/EU/SPin Research IN Graphene/SPRING$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 863098-SPRING$$9info:eu-repo/grantAgreement/ES/MICINN/PCI2019-111933-2$$9info:eu-repo/grantAgreement/ES/MICINN/PID2020-115406GB-I00$$9info:eu-repo/grantAgreement/EUR/MICINN/TED2021-132388B-C43$$9info:eu-repo/grantAgreement/ES/MINECO/RED2018-102833-T 000131440 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000131440 590__ $$a14.7$$b2023 000131440 592__ $$a4.887$$b2023 000131440 591__ $$aMULTIDISCIPLINARY SCIENCES$$b8 / 134 = 0.06$$c2023$$dQ1$$eT1 000131440 593__ $$aBiochemistry, Genetics and Molecular Biology (miscellaneous)$$c2023$$dQ1 000131440 593__ $$aPhysics and Astronomy (miscellaneous)$$c2023$$dQ1 000131440 593__ $$aChemistry (miscellaneous)$$c2023$$dQ1 000131440 594__ $$a24.9$$b2023 000131440 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000131440 700__ $$aMerino-Díez, Nestor 000131440 700__ $$aBerdonces-Layunta, Alejandro 000131440 700__ $$aSanz, Sofía 000131440 700__ $$0(orcid)0000-0001-8253-8741$$aDomínguez-Celorrio, Amelia 000131440 700__ $$0(orcid)0000-0003-2698-2543$$aLobo-Checa, Jorge 000131440 700__ $$aVilas-Varela, Manuel 000131440 700__ $$aPeña, Diego 000131440 700__ $$aFrederiksen, Thomas 000131440 700__ $$aPascual, José I. 000131440 700__ $$aOteyza, Dimas G. de 000131440 700__ $$0(orcid)0000-0002-3260-9641$$aSerrate, David 000131440 773__ $$g14, 6677 [8 pp.] (2023)$$tNature communications$$x2041-1723 000131440 8564_ $$s2897235$$uhttps://zaguan.unizar.es/record/131440/files/texto_completo.pdf$$yVersión publicada 000131440 8564_ $$s2695558$$uhttps://zaguan.unizar.es/record/131440/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000131440 909CO $$ooai:zaguan.unizar.es:131440$$particulos$$pdriver 000131440 951__ $$a2024-11-22-11:56:58 000131440 980__ $$aARTICLE
