Microscopic Picture

ABSTRACTApplication of 57Fe MÖssbauer spectroscopy to the determination of magnetic structural parameters relevant to nanostructural studies is discussed. Variable temperature and applied magnetic field strength investigations are considered in order to illustrate the power of the technique in rendering a microscopic picture of the internal spin structure and dynamical spin relaxation phenomena associated with nanoscale systems. Examples from biology and chemistry, where iron aggregates of nanometer dimensions are encountered, are presented.

Mößbauer Spectroscopy

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.

A [3Fe–3(μ-S)]3+ cluster is reported in which each ferric center has a distorted trigonal pyramidal geometry, with an S = 1/2 ground state for the cluster and unusually anisotropic hyperfine coupling constants as determined by variable temperature magnetometry and Mössbauer spectroscopy.
