Abstract: The dependence of the magnetization reversal on the sweep rate of the applied magnetic field has been studied for single crystals of Fe-8 magnetic molecules. Our experiments have been conducted at temperatures below 1 K and sweep rates of the magnetic field between 10(3) T/s to 10(4) T/s. The systematic shift of the values of the magnetic field at which the magnetization reversal occurs, indicates that this reversal process is not governed by the Landau-Zener transition model. Our data can be explained in terms of the superradiance emission model proposed by Chudnovsky and Garanin.
