NMR in magnetic molecular rings and clusters (II)
F. Borsa, A. Lascialfari, Y. Furukawa
In the last years there has been a great interest in magnetic systems formed by a cluster of transition metal ions covalently bonded via superexchange bridges, embedded in a large…

X-ray magnetic circular dichroism spectra on the superparamagnetic transition metal-ion clusters [Mn12O12(CH3COO)16(H2O)24].2CH3COOH.4H2O (Mn12) and [Fe8O2(OH)12(tacn)6]Br8 9H2O (Fe8)
Paolo Ghigna, Andrea Campana, Alessandro Lascialfari +4
The first X-ray magnetic circular dichroism (XMCD) spectra on the title compounds are presented. In Mn12 the Mn(III) and Mn(IV) contributions are clearly apparent and evidence the…
LiVO(Si,Ge)O, a prototype of a two-dimensional frustrated quantum Heisenberg antiferromagnet
R. Melzi, P. Carretta, A. Lascialfari +4
NMR and magnetization measurements in LiVOSiO and LiVOGeO are reported. The analysis of the susceptibility shows that both compounds are two-dimensional Hei…
