摘要：

In this contribution, the effect of high external magnetic fields upon the Mossbauer spectra of aluminous alpha- and gamma-Fe2O3, of aluminous alpha- and gamma-FeOOH and of aluminous Fe3O4 is reviewed. It is shown that the shapes of these spectra are characteristic of these materials and also to some extent of their crystallinities and Al-for-Fe substitutions. Based upon this evaluation, the potential for application of external-field Mossbauer spectroscopy to soil-related analytical purposes is demonstrated for two soil samples. Limitations of the technique are discussed. Finally, some suggestions for further research in this field are indicated.
