Polycationic Mn₁₂ Single‐Molecule Magnets as Electron Reservoirs with S>10 Ground States

Spin Quantum Tunneling in Single Molecular Magnets: Fingerprints in Transport Spectroscopy of Current and Noise

“…Higher order corrections to the magnetic anisotropy barrier are not essential here. It is known experimentally [15,16,17,18,19,20,21] and theoretically [14] that the anisotropy constants D (N ) depend on the charge state. The transverse anisotropy, Eq.…”

Advances on the nanostructuration of magnetic molecules on surfaces: the case of single-molecule magnets (SMM)

“…This cluster comprises 16 quaternary ammonium carboxylates (bet stand for betaine = + N(CH 3 ) 3 CH 2 COO 2 ) at the periphery, which are expected to favour the ionic immobilization. 34 In a preliminary work, ionic immobilization was successfully achieved on a grafted monolayer of sodium mercaptoethanesulfonate (HS(CH 2 ) 2 SO 3 Na) on Au(111), bearing terminal free -SO 3 2 groups. After dipping the functionalized substrate into a solution of complex 6, room-temperature STM images revealed that at short times of immersion a partial coverage of the gold surface is observed whereas longer immersion times induce the formation of 3D aggregates.…”

Anisotropy barrier reduction in fast-relaxingMn12single-molecule magnets

“…The synthesis of pure crystals containing neutral FR Mn 12 O 12 species have enabled detailed characterizations of their structures and magnetic properties [we note that reduced forms of Mn 12 have also been obtained that also exhibit fast relaxation, [27][28][29][30][31][32] but these are not considered in this study]. In all cases where the FR species are obtained in single-crystal form, X-ray studies show that one or more of the Jahn-Teller (JT) elongation axes associated with the Mn III atoms are abnormally oriented 18,19,21,24,25,33 in comparison to the usual SR form of Mn 12 .…”
