The differential susceptibility, dM/dH, of an {Fe8} -cubane cluster has been measured for magnetic fields up to 54 T at 1.3 and 4.2 K using a pulsed-field technique. The data feature a single strong peak at 42±1 T, corresponding to a ground state level crossing at that field, in excellent agreement with the predicted value, 41±1 T, obtained using a Heisenberg model of the cluster. The theoretical model also accurately accounts for detailed features of the temperature and field dependence of the width and height of the observed peak.
