AbstractThe Landau-Zener multi-crossing relaxation in Mn12 molecule is studied based on the tunnel splitting obtained from the spin-coherent-state path integral including the local stray field. It is found that the spins with larger second-order transverse anisotropic parameters will finish the relaxation before the higher resonance is reached. Such a pre-relaxation seriously modifies the relaxation behavior at higher resonance and makes the distributions of the second-order transverse anisotropic parameters extracted from different resonances un-scaled. Our analysis shows that scaled distributions can be found from the relaxation curves of k=6 and k=7 resonance by including the effect of pre-relaxation.
