Cyclooctatetraenide-based single-ion magnets featuring bulky cyclopentadienyl ligand. [PDF]
Chem Sci, 2022 We report a family of organometallic rare-earth complexes with the general formula (COT)M(Cpttt) (where (COT)2– = cyclooctatetraenide, (Cpttt)– = 1,2,4-tri(tert-butyl)cyclopentadienide, M = Y(III), Nd(III), Dy(III) and Er(III)). Similarly to the prototypical Er(III) analog featuring pentamethylcyclopentadienyl ligand (Cp*)–, (COT)Er(Cpttt) behaves as a

Rotaxane CoII Complexes as Field‐Induced Single‐Ion Magnets [PDF]
Angewandte Chemie, 2021 AbstractMechanically chelating ligands have untapped potential for the engineering of metal ion properties. Here we demonstrate this principle in the context of CoII‐based single‐ion magnets. Using multi‐frequency EPR, susceptibility and magnetization measurements we found that these complexes show some of the highest zero field splittings reported for

Organometallic Single-Ion Magnets [PDF]
Acta Crystallographica Section A Foundations and Advances, 2014 The single-molecule magnets (SMMs) are attracting the increasing interesting due to their potential applications in high density information storage, quantum computing, molecular spintronics, and magnetic refrigeration. This field provides scientists a possible access into the crossover of the classical and quantum world, and a wonderful model to study

Understanding temperature-dependent SU(3) spin dynamics in the S = 1 antiferromagnet Ba2FeSi2O7
npj Quantum Materials, 2023 Quantum magnets admit more than one classical limit and N-level systems with strong single-ion anisotropy are expected to be described by a classical approximation based on SU(N) coherent states.

An Exchange Mechanism for the Magnetic Behavior of Er3+ Complexes
Molecules, 2021 We study the magnetic properties of the erbium based compounds, Na9[Er(W5O18)2] and [(Pc)Er{Pc{N(C4H9)2}8}]·/−, in the framework of an effective spin exchange model involving delocalized electrons occupying molecular orbitals.

Reciprocating Thermal Behavior in Multichannel Relaxation of Cobalt(II) Based Single Ion Magnets
Magnetochemistry, 2021 A series of mononuclear Co(II) complexes showing slow magnetic relaxation is assessed from the point of view of relaxation mechanisms. In certain cases, the reciprocating thermal behavior is detected: On cooling, the slow relaxation time is prolonged ...
