Abstract

Mössbauer spectra of ferritin and its pharmaceutical analogue Ferrum Lek, both containing nanosized hydrous ferric oxides cores in the forms of ferrihydrite and akaganéite, respectively, were measured in the temperature range 295-90 K. An anomalous line broadening with temperature decrease was observed for ferritin below ∼150 K and for Ferrum Lek below ∼130 K. Some anomalies were also observed below these temperatures for spectral area and quadrupole splitting.
