Abstract

Mössbauer spectra obtained from a sample of the iron-storage protein haemosiderin have been analysed in both the collective excitation and superparamagnetic relaxation temperature regions. The results indicate that the low temperature spectra cannot be explained in terms of collective excitations, and that there must be other effects leading to the observed distribution of hyperfine fields.
