Some applications of Mössbauer spectroscopy to the study of magnetic oxides

Mössbauer spectroscopy is a useful tool for characterizing certain properties of magnetic materials. Much of the information available from Mössbauer spectroscopy requires a detailed analysis of hyperfine parameters; a brief discussion of this analysis for Fe⁵⁷in the presence of mixed magnetic dipole and electric quadrupole interactions is given. Several examples of experimental studies on iron containing magnetic oxides are discussed which illustrate some of the more common uses of Mössbauer spectroscopy in applied magnetism. Experimental studies related to phase analysis, phase transitions, relative site populations, determination of magnetic ordering temperatures, and magnetic structure investigations are included.
