Mössbauer spectra of the oxide spinels Fe1-xZnxCr2O4 and Fe1-xMgxCr2O4, with x=0.0 to 0.5, exhibit a singlet only. This suggests that, in complex spinel solid-solutions, substitution of cations into the second coordination sphere does not contribute to anisotropy of the electric field gradient at the nucleus of tetrahedral ferrous iron.
