The first measurements of magnetization hysteresis loops on a diluted single crystal of [(Pc)2Ho]-.TBA+ (Pc = phthalocyaninato, TBA = tetrabutylammonium) in the subkelvin temperature range are reported. Characteristic staircase-like structure was observed, indicating the occurrence of the quantum tunneling of magnetization (QTM), which is a characteristic feature of SMMs. The quantum process in the new lanthanide SMMs is due to resonant quantum tunneling between entangled states of the… Expand
Enhancing the quantum properties of manganese-lanthanide single-molecule magnets: observation of quantum tunneling steps in the hysteresis loops of a {Mn12Gd} cluster.
A new structural type in mixed Mn–Ln SMMs having a {Mn12Gd} 38+ core is reported, in which clear QTM steps have been observed in the hysteresis loops of a mixed 3d–4f SMM for the first time. Expand
Hyperfine-Interaction-Driven Suppression of Quantum Tunneling at Zero Field in a Holmium(III) Single-Ion Magnet.
An extremely rare non-Kramers holmium(III) single-ion magnet (SIM) is reported to be stabilized in the pentagonal-bipyramidal geometry by a phosphine oxide with a high energy barrier of 237(4) cm-1 .Expand
Highly reduced double-decker single-molecule magnets exhibiting slow magnetic relaxation.
Low-temperature MCD studies reveal for the first time magnetization hystereses for the super-reduced dianionic and trianionic states of Pc2Ln. Expand
Spin dynamics in the negatively charged terbium (III) bis-phthalocyaninato complex.
It is found that the barrier Delta and the tunneling rates change from sample to sample and especially the diamagnetically diluted [Pc(2)Tb](-) molecules appear affected by the sample's magneto/thermal history, emphasize that matrix arrangements around [P c(2]Tb]--) can appreciably alter the splitting of the crystal field levels, its symmetry, and hence, the spin dynamics.

Single-molecule magnetism in a single-ion triamidoamine uranium(V) terminal mono-oxo complex.
The first monometallic uranium(V), 5f SMM, is reported, where the physical properties result from imposing a strongly axial ligand field with C3v symmetry, the first unambiguous confirmation that uranium (V) complexes can indeed exhibit SMM behavior. Expand

Zero-Field Quantum Tunneling of the Magnetization in a Series of High Energy-Barrier Dysprosium (III) Single-Molecule Magnets
Energy barriers to magnetisation reversal (Ueff) in single-molecule magnets (SMMs) have vastly increased recently, but only for the dysprosocenium SMM [Dy(Cpttt)2][B(C6F5)4] (Cpttt = C5H2tBu3-1,2,4)Expand
Modulating the magnetic relaxation of lanthanide-based single-molecule magnets

A mononuclear dysprosium complex featuring single-molecule-magnet behavior.
The Dy ion, which possesses a Kramers ground state of H15/2, is an appealing paramagnetic source for the construction of SMMs in a suitable ligand-field symmetry and strength, and all three reported types of single-ion magnets are found with a high-order single axis defining the local symmetry.
