Nutzen der 3d‐4f Koordination: Molekulares Quanten‐Feder‐Magnet‐Verhalten in axialen Ni2Ln Komplexen

Angewandte Chemie, EarlyView.
Wir berichten über heterotrimetallische Ni2Ln Komplexe, die Austauschfeder‐Magnete auf molekularer Ebene nachahmen. CASSCF Rechnungen zeigen kollineare Anisotropieachsen, während µSQUID Studien langsame Relaxation und offene Hysterese in Ni2Tb, Ni2Dy, und Ni2Ho offenbaren.

Leveraging 3d‐4f Coordination: Molecular Quantum Spring‐Magnet Behavior in Axial Ni2Ln Complexes

Angewandte Chemie International Edition, EarlyView.
We report heterotrimetallic Ni2Ln complexes mimicking exchange spring magnets at the molecular level. CASSCF calculations show collinear anisotropy axes, while µSQUID studies reveal slow relaxation and open hysteresis in Ni2Tb, Ni2Dy, and Ni2Ho. Ferromagnetic 3d–4f coupling and anisotropy alignment enhance bistability, offering promise for quantum, and
