The one‐monolayer (1ML) samples of {Cr10} sublimated on Ag(111) and Cu(111) show slightly different applied magnetic field dependence of XMCD signal. The field‐dependence of the magnetization evolves from a lower curve for the 1ML {Cr10} samples to a curve resembling the bulk one as the number of layers is increased, as shown in a 14ML sample. Monte Carlo simulations allow rationalizing the magnetization curves of the 1ML samples in terms of a reduction of the cluster ground‐state total spin, S  =  3 or S  =  6, as a consequence of variations in the intra‐wheel coupling interactions induced by the on‐surface deposition. The sensitivity of the magnetic configuration of {Cr10} to minor distortions of the intramolecular conformation might be exploited to control magnetism by external stimuli for applications. info:eu-repo/grantAgreement/ES/DGA-FSE/E12-23R-RASMIA info:eu-repo/grantAgreement/ES/AEI/PID2020-115159GB-I00/AEI/10.13039/501100011033 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.3 2023 CHEMISTRY, MULTIDISCIPLINARY 72 / 231 = 0.312 2023 Q2 T1 MATERIALS SCIENCE, MULTIDISCIPLINARY 153 / 439 = 0.349 2023 Q2 T2 1.194 2023 Mechanics of Materials 2023 Q1 Mechanical Engineering 2023 Q1 8.4 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Ferrari, Ludovica Sedona, Francesco Arauzo, Ana Universidad de Zaragoza (orcid)0000-0002-5999-341X Rubín, Javier Universidad de Zaragoza (orcid)0000-0003-1029-3751 Luzón, Javier (orcid)0000-0002-9208-0807 Herrero-Albillos, Julia Universidad de Zaragoza (orcid)0000-0002-0901-8341 Panighel, Mirco Mugarza, Aitor Rancan, Marzio Sambi, Mauro Armelao, Lidia Bartolomé, Juan Universidad de Zaragoza (orcid)0000-0002-6517-1236 Bartolomé, Fernando (orcid)0000-0002-0047-1772 2003 395 Universidad de Zaragoza Dpto.
