Graphical Abstract
Einzelmolekülmagnete: Ein quadratisch-pyramidaler Dysprosium-Cluster mit fünf Metallzentren (siehe Bild) zeigte langsames magnetisches Relaxationsverhalten bei Temperaturen bis 40 K. Die thermische Energiebarriere für die Magnetisierungsrelaxation dieses Einzelmolekülmagneten ist 530 K; es ist damit die höchste Barriere, die für Clusterverbindungen der d- und f-Elemente bisher beobachtet wurde.
