Magnetic measurements indicate that all the complexes show a field-induced single-ion magnet behavior under a small applied dc field. The magnetic analysis shows the relevance of the different spin relaxation mechanisms in the magnetic relaxation of the CeIII compounds, with special emphasis on the local-mode process. Multiconfigurational calculations were also performed to get more information on the axiality of the compounds.13 p.application/pdfengcc-by (c) Mautner, Franz A. et el., 2022http://creativecommons.org/licenses/by/3.0/es/Propietats magnètiquesIonsLligandsMagnetic propertiesIonsLigandsinfo:eu-repo/semantics/article7247302023-03-24info:eu-repo/semantics/openAccess
