It is shown that ferritin follows N6el-Arrhenius behavior over eight orders of magnitude in frequency. A pre-exponential relaxation time of % ~ 10-Us and an anisotropy energy of Ea/k B = 318 K are obtained. A net core moment of 300g B, in agreement with theoretical predictions, is determined from high-field magnetisation isotherms.
