Abstract

Two prominent Fe3+ centres were observed by ESR in alpha -TeO2:Fe single crystals. One of them exhibits C2 symmetry (Fe3+(C2) centre) and the other one exhibits C 1 symmetry and also superhyperfine interactions with two hydrogens (Fe3+-2H-V0(C1) centre). The Fe 3+(C2) centre is believed to be an interstitial Fe 3+ ion; the nature of its superhyperfine interaction with neighbouring Te nuclei contributes to this assignment. The Fe 3+-2H-V0(C1) centre is attributed to a substitutional Fe3+ ion with two neighbouring hydrogens and a local oxygen vacancy.
