Abstract

Mossbauer spectroscopy obtained with the sample at low T (293, 77 and 4.2 K) and subject to large magnetic fields is discussed in terms of its use in analysing goethite, akaganeite and lepidocrocite and the common growth precursor ferrihydrite. Experiments on well-characterized synthetic samples provided benchmark results. A relatively simple means of quantitative analysis was used in which sets of Voigtian-shaped lines were summed and least-squares fitted. The results are discussed in terms of the magnetic structures of each mineral.
