Abstract:
Electron spin resonance spectra of non-Kramers bivalent iron (Fe2+2+) ions have been detected in synthetic and natural beryl crystals with an iron impurity. The observed ESR spectra have been attributed to resonance transitions of Fe2+2+ ions from the ground (singlet) state to excited (doublet) levels with the splitting ΔΔ = 12.7 cm−1−1 between the levels. The experimental angular and frequency dependences of the resonance field of the ESR signal have been described by the spin Hamiltonian with the effective spin SS = 1. The analysis of the ESR data and optical absorption spectra indicates that the Fe2+2+ ions are situated in tetrahedral positions and substitute Be2+2+ cations in the beryl structure.
