Abstract: | In this paper the Mossbauer spectra of a chromite at 140K 200K and 298K were measured. Next nearest neighbor effects were
used to explain the spectra of the chromite, and multiple doublets of Fe2+ ions on the A sites were caused by the different cation combinations on 12 next nearest neighbor B sites. The quandrupole
splitting of each of mult iple Fe2+ doublets decreases with increasing temperature. |
