In this work, we explore the structural, electronic, and magnetic properties of monolayer CoCl2 grown epitaxially on Au(111) using a multitechnique approach. Our results reveal that epitaxial CoCl2 exhibits ferromagnetic order below 24 K with strong in-plane magnetic anisotropy, setting it apart from other TMDH materials. Additionally, we identify in-gap states arising from the CoCl2–Au(111) interface, which provide insights into its electronic behavior. These findings position CoCl2 as a versatile 2D material for spintronic applications and nanoscale devices, bridging the gap between fundamental research and real-world technological solutions. 000161092 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E12-23R$$9info:eu-repo/grantAgreement/EC/H2020/101064332/EU/Addressing molecular spin qubits by ESR-STM/QMOLESR$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 101064332-QMOLESR$$9info:eu-repo/grantAgreement/ES/MCIU/PID2020-114252GB-I00$$9info:eu-repo/grantAgreement/EUR/MCIU/TED2021-130292B-C42$$9info:eu-repo/grantAgreement/EUR/MCIU/TED2021-132388B-C43$$9info:eu-repo/grantAgreement/ES/MICINN AEI/PID2022-138750NB-C21$$9info:eu-repo/grantAgreement/ES/MCINN/PID2022-140845OB-C63$$9info:eu-repo/grantAgreement/ES/MCINN/PID2022-140845OB-C65 000161092 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000161092 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000161092 700__ $$aHadjadj, Sebastien Elie 000161092 700__ $$aAguirre-Baños, Andrea 000161092 700__ $$aLongo, Danilo 000161092 700__ $$aPinar Solé, Andrés 000161092 700__ $$aStetsovych, Oleksandr 000161092 700__ $$aCandia, Adriana Elizabet 000161092 700__ $$aAngulo-Portugal, Paula 000161092 700__ $$aCaldevilla, David 000161092 700__ $$aChoueikani, Fadi 000161092 700__ $$aCorso, Martina 000161092 700__ $$0(orcid)0000-0002-3260-9641$$aSerrate Donoso, David 000161092 700__ $$0(orcid)0000-0003-2698-2543$$aLobo-Checa, Jorge 000161092 700__ $$aJelínek, Pavel 000161092 700__ $$aIlyn, Maxim 000161092 700__ $$aRogero, Celia 000161092 773__ $$g19, 22 (2025), 20693-20701$$pACS Nano$$tACS NANO$$x1936-0851 000161092 8564_ $$s10955686$$uhttps://zaguan.unizar.es/record/161092/files/texto_completo.pdf$$yVersión publicada 000161092 8564_ $$s3115534$$uhttps://zaguan.unizar.es/record/161092/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000161092 909CO $$ooai:zaguan.unizar.es:161092$$particulos$$pdriver 000161092 951__ $$a2025-10-17-14:26:56 000161092 980__ $$aARTICLE
