Abstract

The magnetic properties of the ferromagnetic ring-shaped single-molecule magnet (n-BuNH3)12[(CuCl)6 (AsW 9O33)2] 6H2O, known as Cu 6, have been studied by electron spin resonance (ESR). The ESR spectra show several sharp absorptions, which originates from the multiplet splitting of the high spin ground state S 3. Meanwhile, the frequency-field plot of the observed ESR shows a gap at zero-field suggesting the existence of an anisotropic exchange interaction in the system. Moreover, forbidden ESR transitions of ΔSz 2 have been also observed where the origin comes from the mixing of the spin state by virtue of the transverse field component of the anisotropy.
