Autor: Lorusso, G., Sharples, J. W., Palacios, E., Roubeau, O., Brechin, E. K., Sessoli, R., Rossin, A., Tuna, F., McInnes, E. J. L., Collison, D., Evangelisti, M.

The magnetocaloric effect of gadolinium formate, Gd(OOCH)3, is experimentally determined down to sub-Kelvin temperatures by direct and indirect methods. This 3D metal-organic framework material is characterized by a relatively compact crystal lattice

Influence of antisymmetric exchange interaction on quantum tunneling of magnetization in a dimeric molecular magnet Mn6

Autor: Bahr, S., Milios, C. J., Jones, L. F., Brechin, E. K., Mosser, V., Wernsdorfer, W.

Publikováno v: Phys. Rev. B 78, 132401 (2008)

We present magnetization measurements on the single molecule magnet Mn6, revealing various tunnel transitions inconsistent with a giant-spin description. We propose a dimeric model of the molecule with two coupled spins S=6, which involves crystal-fi

Direct Observation of Quantum Coherence in Single-Molecule Magnets

Autor: Schlegel, C., van Slageren, J., Manoli, M., Brechin, E. K., Dressel, M.

Publikováno v: Phys. Rev. Lett. 101, 147203 (2008)

Direct evidence of quantum coherence in a single-molecule magnet in frozen solution is reported with coherence times as long as T2 = 630 ns. We can strongly increase the coherence time by modifying the matrix in which the single-molecule magnets are
