Description

The presence of substituting elements in magnetically ordered structure of crystals may change the shape of Moessbauer spectra of these materials. This fact was used to determine whether there is an ionic substitution of Ni, Co, Mn and Al for Fe in synthetic goethites. The approximate distribution function of the effective magnetic field in the Fe nucleus ρ' (Hn) was obtained from the Moessbauer spectra. It was found that the mean value of ρ' (Hn) and its integral width can be taken as a measure of substitution in goethite. (orig.)
