Abstract: Abstract Molecular clusters of interacting paramagnetic metal ions show a slow dynamics of the magnetization at low temperature, which is characterized by quantum effects. Oscillation of the tunnel splitting is observed when the field is applied along the hard axis due to the topological interference of the tunnel pathways. An unsual isotope effect, based on the magnetic moment of the nuclei, is observed in the dynamics of the magnetization in the quantum regime.
