Observation of unusual slow-relaxation of the magnetisation in a Gd-EDTA chelate

A Gadolinium EDTA chelate displays characteristic isotropic behav- iour common of GdIII complexes under zero applied magnetic field, and anisotropic behaviour arising from dipolar coupling and weak spin–phonon coupling under an applied magnetic field. This surprising magnetic behaviour for GdIII is investigated using SQUID magnetometry and rationalized through theoretical calculations.crosscheck: This document is CrossCheck deposited related_data: Supplementary Information related_data: Crystal Structure Data identifier: Le Tuan Anh Ho (ResearcherID) identifier: Liviu Ungur (ORCID) identifier: Liviu Ungur (ResearcherID) copyright_licence: The Royal Society of Chemistry has an exclusive publication licence for this journal history: Received 16 October 2015; Accepted 19 October 2015; Advance Article published 11 November 2015; Version of Record published 24 November 2015status: publishe
