Magnetization reversal of Mn12 cluster has been studied in ultra-fast sweeping magnetic fields. Below 3 K, a jump of magnetization is found in magnetization process in pulsed fields. A temperature dependence of magnetization saturates below the blocking temperature of 1.3 K. Time and critical field of the reversal show strong sweep velocity dependences.
