Mössbauer spectra of dilute Fe3+ in LiScO2 and mullite have been studied over the temperature range 4 to 295°K. The hyperfine spectrum of the doublet ± 1 2 in mullite has been identified up to room temperature along with the spectrum of the doublet ± 5 2, which indicates that the spin-lattice relaxation times of doublets ± 5 2 and ± 1 2 are very similar in this system. The high value of the E D ratio for tetrahedral Fe3+ in mullite has made possible the observation of well-resolved hyperfine spectra of the doublet ± 1 2 even in zero applied field.
