Abstract
The presence of substituting elements in magnetically ordered structure of crystals may change the shape of Mössbauer 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 nucleusp′ (Hn) was obtained from the Mössbauer spectra. It was found that the mean value ofp′ (Hn) and its integral width can be taken as a measure of substitution in goethite.
