Description
We report 1H nuclear magnetic resonance spin-lattice relaxation rate (NSLR) measurements as a function of temperature (1.5-4.2 K) and as a function of applied magnetic field (0.2-8.2 T) in the molecular magnet [(PhSiO2)6Cu6(O2SiPh)6] in short Cu6. The results are explained in terms of a simple model whereby the NSLR is driven by the fluctuations of the local hyperfine field due to the reorientation of the total spin of the molecule in its ground state. From the analysis of the data, we infer the temperature and field dependence of the characteristic rate of the fluctuations of the total magnetization of the Cu6 ring in its ground state.
