Graphical Abstract

Treppenförmige Strukturen in den Hystereseschleifen bei 0.04 K (siehe Bild) werden von dotierten Einkristallen von TBA[(Pc)₂ equation image ] (Pc=Phthalocyaninato, TBA=Tetrabutylammonium), dem ersten Lanthanoid-Einzelmolekülmagneten, erzeugt. Sie werden mit einem resonanten Quantentunneln der Magnetisierung zwischen verschränkten Zuständen des Elektronen- und Kernspinsystems erklärt. Der Dy-Komplex wurde ebenfalls untersucht.
