57Fe Mössbauer Spectroscopy as a Tool for Study of Spin States and Magnetic Interactions in Inorganic Chemistry

Abstract

In this mini-review of our research group’s activity, the application of 57Fe Mössbauer spectroscopy in studies of electronic structure, coordination environment, and magnetic interactions in an interesting series of Fe(II/III) compounds selected is discussed. We selected two prominent phenomena that arose during investigations of selected groups of compounds carried out at different periods of time: (1) very high magnetic hyperfine fields observed at low temperatures; (2) changes in the oxidation state of the central iron atom of complexes in the solid state during interactions with gaseous O2/H2O mixtures, resulting in spin crossover (SCO).

Mössbauer spectroscopic investigations on iron oxides and modified nanostructures: A review

“…Research has been extended in the field of environmental catalyst and energy catalyst for phase identification of the catalyst using Mössbauer technique [ 44 ]. Also people have focus on the review of high magnetic properties at low temperature and spin states in the solid-state interaction with gaseous O 2 /H 2 O mixture of central iron atom complexes [ 48 ]. In this perspective, the present reviews attempt to capture specific areas of research using Mössbauer spectroscopy in the hopes of inspiring and encouraging the scientific community to pursue new insights in this research methods.…”

“…The structure of the spectra obtained from 57 Fe Mössbauer spectroscopy were discussed in the review article by Ernő et al [ 41 , 48 ]. The radioactive source is generally embedded in the non-magnetic cubic material with high Debye temperature.…”

A Review of the Current State of Magnetic Force Microscopy to Unravel the Magnetic Properties of Nanomaterials Applied in Biological Systems and Future Directions for Quantum Technologies

“…Mössbauer spectroscopy is a versatile technique to study the interaction of certain isotopes with their surroundings [ 42 ]. This technology enables the hyperfine interactions between the nuclei and electrons to be measured with an accuracy of 14–15 magnitude orders [ 43 ].…”
