abstract:
The low-temperature spin dynamics in molecular rings with a finite number (N less than or equal to 10) of magnetic ions was studied by means of H-1 NMR. When an external magnetic field (B) induces a crossing between energy levels, peaks are observed in the spin-lattice relaxation rate of protons, 1/T-1(B), at constant temperature. We discuss similarities and differences in the data from three different rings: Fe10, Fe6:Li and Cr8.
