The average blocking temperatures of ferritin molecules containing differing amounts of iron were determined by Mossbauer spectroscopy. The results imply that the magnetic anisotropy of the ferritin core particles is a function of particle volume. By addition of57Fe to ferritin core particles it was determined that, at a given temperature within the superpara-magnetic temperature region, the "last-in" ferric ions have average relaxation times that are shorter than those of the bulk ferric ions. © 1991 J.C.
