Polymerisation of the Dysprosium Acetate Dimer Switches on Single-Chain Magnetism

Teaching old dimers new tricks: The magnetic properties of the known dysprosium acetate dimer were re‐investigated, confirming that there is no slow relaxation of the magnetisation. In contrast, the newly synthesised polymeric dysprosium acetate chain shows single‐chain magnetism (see picture), maki...

Zusammenfassung:Teaching old dimers new tricks: The magnetic properties of the known dysprosium acetate dimer were re‐investigated, confirming that there is no slow relaxation of the magnetisation. In contrast, the newly synthesised polymeric dysprosium acetate chain shows single‐chain magnetism (see picture), making it the first homo‐spin lanthanide single‐chain magnet.
