Title: A Study of Co, Ni, Mn, and Al Containing Goethites by Mossbauer Spectroscopy
Abstract: To determine whether there is an ionic substitution of Ni, Co, Mn, and Al for Fe in synthetic goethites these materials have been studied by Mossbauer spectroscopy at various temperatures ranging from 77 to 400 K. It is found that the presence of substituting elements in magnetically ordered structure of crystals may change the shape of Mossbauer spectra of these materials. The approximate distribution function of the effective magnetic field in the Fe nucleus p(Hn) is obtained from the Mossbauer spectra. It is noted that the mean value of p(Hn) and its integral width can be taken as a measure of substitution in goethites.
