The [Dy(tta)3(L)] complex behaves as a single ion magnet both in its crystalline phase and in solution. Experimental and theoretical magnetic anisotropy axes perfectly match and lie along the most electro-negative atoms of the coordination sphere. Both VSM and MCD measurements highlight the robustness of the complex, with persistence of the memory effect… (More)
X-Ray structure, photophysical and magnetic properties have been explored for the binuclear gadolinium(III) coordination complex based on bridging tetrathiafulvalenecarboxylate radical cations [Gd(hfac)(3)(micro-TTF (+)COO(-))](2).
A one-dimensional compound has been constructed through a Yb III ion and bridging redox-active deprotonated 4,5-bis(carboxylic)-4 1 ,5 1-methyldithiotetrathiafulvene. This polymer displays slow magnetic relaxation due to the planar magnetic anisotropy of the Yb III , which has been experimentally determined.
Single-crystal angular-resolved magnetometry and wavefunction-based calculations have been used to reconsider the magnetic properties of a recently reported Dy(III)-based single-molecule magnet, namely [Dy(hfac)3(L(1))] with hfac(-) = 1,1,1,5,5,5-hexafluoroacetylacetonate and L(1) =… (More)

Achieving magnetic remanence at single isolated metal sites dispersed at the surface of a solid matrix has been envisioned as a key step toward information storage and processing in the smallest unit of matter. Here, we show that isolated Dy(III) sites distributed at the surface of silica nanoparticles, prepared with a simple and scalable two-step process,… (More)
The complex [Dy(L)(tta) 3 ] with L the chiral 3-(2-pyridyl)-4-aza-helicene ligand (tta − = 2-thenoyltrifluoroaacetonate) has been synthesized in its racemic form and structurally and magnetically characterized. [Dy(L)(tta) 3 ] behaves as a single molecule magnet in its crystalline phase with the opening of a hysteresis loop at 0.50 K. These magnetic… (More)
