Reducing this fundamental property into strictly two-dimensions was proposed in metal-organic coordination networks, but thus far has eluded experimental realization. In this work, we demonstrate that extended, cooperative ferromagnetism is feasible in an atomically thin two-dimensional metal-organic coordination network, despite only ≈ 5% of the monolayer being composed of Fe atoms. The resulting ferromagnetic state exhibits an out-of-plane easy-axis square-like hysteresis loop with large coercive fields over 2 Tesla, significant magnetic anisotropy, and persists up to TC ≈ 35 K. These properties are driven by exchange interactions mainly mediated by the molecular linkers. Our findings resolve a two decade search for ferromagnetism in two-dimensional metal-organic coordination networks. info:eu-repo/grantAgreement/ES/AEI/PID2019-107338RB-C64 info:eu-repo/grantAgreement/ES/DGA/E12-20R info:eu-repo/grantAgreement/ES/DGA/E13-20R info:eu-repo/grantAgreement/EUR/INTERREG V-A/EFA 194-16-TNSI info:eu-repo/grantAgreement/ES/MICINN-AEI/PRTR-C17.I1 info:eu-repo/grantAgreement/ES/MICINN/PID2019-103910GB-I00 info:eu-repo/grantAgreement/ES/MICINN/PID2020-115159GB-I00 info:eu-repo/grantAgreement/ES/MINECO/RED2018-102833-T info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 15.7 2024 MULTIDISCIPLINARY SCIENCES 10 / 136 = 0.074 2024 Q1 T1 4.761 2024 Biochemistry, Genetics and Molecular Biology (miscellaneous) 2024 Q1 Physics and Astronomy (miscellaneous) 2024 Q1 Chemistry (miscellaneous) 2024 Q1 23.4 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Hernández-López, Leyre (orcid)0000-0001-9713-5603 Otrokov, Mikhail M.
