Analysis of paramagnetic centers for threevalent iron in aluminosilicates

We present the results of investigation of the defects in fluorine aluminosilicates from the Volyn-field Al2 [SiO4][F,OH]2 by the Electron Paramagnetic Resonance (EPR) method. The studies were carried out on the spectrometer Bruker ER 220D. Three types of EPR spectra of single centers were obtained....

Description
Summary:We present the results of investigation of the defects in fluorine aluminosilicates from the Volyn-field Al2 [SiO4][F,OH]2 by the Electron Paramagnetic Resonance (EPR) method. The studies were carried out on the spectrometer Bruker ER 220D. Three types of EPR spectra of single centers were obtained. Their angular dependence was also investigated. The obtained EPR spectra correspond to the paramagnetic ion Fe3+ in the high-spin state S = 5 2. Three types of paramagnetic centers were found: one with cubic-symmetry and two with orthorhombic- symmetries.
