Abstract

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.
