The number of 61Ni Mössbauer studies, although small, indicates that definitive measurements are possible once experimental obstacles have been overcome. The experimental method and hyperfine interactions in 61Ni are discussed briefly, followed by a review of results obtained from 61Ni Mössbauer experiments during the last 10 years. The results are discussed in relation to the determination of spin structures, the study of electronic transitions, and the study of hyperfine interactions.

AbstractBiotites from three peaty gleyed podzol soil profiles on ranite bedrock were examined to investigate the oxidation of the octahedral Fe during weathering. Oxidation of these biotites as determined by Mössbauer spectroscopy shows a good correlation with the in situ measured soil Eh values of the sampled horizons. In every soil profile the highest Eh measured is in the A horizon and the lowest in the C horizon. Similarly, biotites from the A horizons are the most oxidized compared with those from the lower horizons. In most of the samples the oxidation is accompanied by loss of K+ from the lattice, as demonstrated by a moderate degree of vermiculitization.
