Abstract

Mössbauer spectra of Fe(Cr, Al)₂O₄ spinels are reported and interpreted using partial quadrupole splitting theory. Fe²⁺T site quadrupole splittings are calculated for different next-nearest neighbour configurations. Assuming random distribution of the Cr³⁺ and Al³⁺ in the octahedral M sites, good semiquantitative agreement between calculated and observed quadrupole splittings and absorption intensities is obtained.
